RV Loans for Converted Vans: Which Lenders Accept Them

Most RV lenders require RVIA certification, ruling out custom vans. These lenders finance converted vans in 2026, with rates and requirements compared.

The Van Guide

RV loans are the best financing product for a van conversion on paper: longer terms than personal loans (up to 20 years), lower interest rates (often 2–4 percentage points below unsecured lending), and higher maximum amounts. A buyer financing a $90,000 professional conversion through a 15-year RV loan at 7% pays roughly $809 per month. The same amount as a 5-year personal loan at 11% costs $1,960 per month.

The problem is access. Most RV lenders built their underwriting around factory-produced recreational vehicles from RVIA-certified manufacturers. A converted Sprinter from a custom builder does not fit that model, and many lenders will decline the application before it reaches underwriting.

This article covers which RV lenders will finance a converted van, what they require, and how to position a conversion for RV loan approval.

Why Most RV Lenders Require RVIA Certification

RVIA certification is a voluntary manufacturer program administered by the Recreation Vehicle Industry Association. Certified manufacturers agree to build units that meet NFPA 1192 (the national fire protection standard for RVs), and RVIA conducts periodic plant inspections to verify compliance.

For lenders, RVIA certification serves three practical functions:

  1. Standardized safety inspection. The lender knows the unit was built to a recognized standard and inspected by a third party.
  2. Manufacturer accountability. If a defect causes damage, there is a certified manufacturer with insurance and warranty obligations — not an individual or a small shop with limited recourse.
  3. Resale baseline. RVIA-certified units from known manufacturers have resale comps. A 2024 Winnebago Revel has a market value. A one-off custom conversion does not.

This is why RVIA certification is not a regulatory requirement for RV loans — it is a risk-management shortcut. Lenders that skip this requirement substitute other due diligence: appraisals, build documentation, photos, and sometimes in-person inspections.

RV Lenders and Their Converted Van Policies

The RV lending market is concentrated among a handful of specialty lenders and banks. Here is what each requires for converted vans, based on their published materials and lending criteria.

Good Sam Finance Center

Good Sam Finance Center is one of the largest dedicated RV lenders in the United States, operating as a lending marketplace powered by Trident Funding that connects borrowers with a network of banks and credit unions.

  • Loan amounts: $10,000 minimum, up to $2,000,000. Borrowers with credit scores of 600–679 are capped at $50,000 maximum.
  • Rates: Starting at 6.12% APR for the best-qualified borrowers (FICO 800+, $150,000+ loan). Mid-tier example: 10.11% APR for a $25,000–$49,000 loan with a 700–739 FICO. Rates increase significantly for scores below 700.
  • Terms: 6 to 20 years. 20-year terms available for loans $50,000+; 15-year terms for $25,000+; 6–12 years for loans under $25,000.
  • Down payment: Zero down available for loans up to $100,000 per their FAQ. Standard: 10–20% depending on loan size, credit, and vehicle age.
  • Credit score: Minimum 600 for purchases, 700 for refinances.
  • Converted vans: Good Sam explicitly lists “Class B/C Conversions” as an eligible RV type, alongside bus conversions and overland/adventure RVs (Earth Roamer, TouRig, etc.).
  • RVIA requirement: Not mentioned anywhere on their site. The explicit listing of “Class B/C Conversions” as eligible suggests RVIA certification is not a hard requirement, though individual lenders in their network may apply their own criteria during underwriting.
  • Other requirements: RV must be titled as recreational use. Maximum age: 20 model years. Maximum mileage: 99,999 (gas) or 150,000 (diesel). Non-mechanical/visual inspection may be required. Loans $150,000+ require a Personal Financial Statement.
  • Not financed: Full-timers, park models, tiny homes, rental units.
  • Key detail: Good Sam is a marketplace, not a single lender. The specific bank that underwrites the loan may have its own requirements. Funding timeline is 7–12 business days from approval.

Credit Unions (Mountain America and Others)

Credit unions sometimes offer more flexible underwriting than national RV lenders because they make lending decisions locally rather than through automated systems.

Mountain America Credit Union (serving UT, AZ, NV, NM, ID, MT, and other western states) offers RV loans starting at 7.49% APR (with a 0.25% checking account discount). Their website lists motorhomes, fifth wheels, campers, and toy haulers as eligible vehicle types but does not address custom van conversions one way or the other. A phone call is required to determine whether a custom build titled as a motorhome would qualify.

  • Key detail: If Mountain America does not serve your area, check local credit unions with RV loan products. Credit unions are often the most flexible path for non-certified conversions that exceed personal loan limits, because they evaluate applications individually rather than running them through automated systems that check an RVIA box.

Lenders That Do Not Finance Converted Vans

Several lenders that appear in RV financing searches are not viable for custom van conversions. Knowing this upfront saves time.

Southeast Financial

Southeast Financial is one of the larger RV financing brokers in the US, but they explicitly exclude conversion vans from their eligible vehicle list. They finance factory-built Class B motorhomes (Winnebago, Thor, etc.) but not aftermarket van conversions — regardless of builder or certification status. Their rates start at 6.24% APR with terms up to 20 years, but only for eligible factory RVs.

Essex Credit / Bank of the West / BMO

Essex Credit, which operated under Bank of the West, was a well-known RV lender. BMO acquired Bank of the West in February 2023 and subsequently sold its $7.2 billion RV loan portfolio to a KKR-led group in December 2023. As of April 2026, Essex Credit’s website is unreachable and BMO does not prominently list RV lending products. This program should be considered effectively discontinued.

Medallion Bank

Medallion Bank is a dealer-only lender (no direct-to-consumer applications) that requires vehicles to be listed in the JD Power/NADA Appraisal Guide. Custom van conversions do not have NADA values, which effectively excludes them. Medallion also specializes in non-prime borrowers — their rates reflect that risk profile.

What RV Lenders Require for a Converted Van

When an RV lender does accept a non-factory conversion, the documentation requirements are more extensive than for a factory unit. Expect to provide:

Vehicle documentation:

  • VIN and title (must show motorhome/housecar classification in most cases)
  • Base vehicle purchase price and date
  • Current mileage
  • Registration showing RV/motorhome classification

Build documentation:

  • Itemized build cost breakdown (materials, labor, components)
  • Photos of the completed conversion (interior layout, electrical panel, plumbing, sleeping area, kitchen, bathroom if applicable)
  • Builder invoice or contract (for professional builds)
  • Receipts for major components (solar, batteries, appliances, HVAC)

Appraisal:

  • Many lenders require a professional appraisal for custom conversions
  • The appraisal establishes the loan-to-value ratio
  • Appraisal costs vary; ask the lender whether they have approved appraisers and what the typical fee is before committing
  • Some lenders accept a certified appraisal from an NADA-recognized appraiser; others have specific appraiser requirements

Title status:

  • Most RV lenders require the vehicle to be titled as a motorhome, housecar, or equivalent — not as a commercial cargo van
  • If the van has not been retitled, this needs to happen before the loan closes
  • Retitling requirements vary by state. In California, see our California registration guide for the process

The Timing Problem

RV loans work best when financing a completed vehicle — the lender inspects (or appraises) a finished unit and lends against its value. This creates a timing challenge for van conversions:

Scenario 1: Buying a completed conversion. This is the cleanest path to an RV loan. The van is finished, titled as a motorhome, and has a documented value. The buyer applies for the loan, the lender appraises the unit, and the transaction closes like any vehicle purchase. The lender will also require proof of camper van insurance before disbursing funds.

Scenario 2: Financing a build in progress. This is where RV loans break down. The builder needs deposits and progress payments during the build. The RV lender wants to finance a completed unit. There is no standard product that bridges this gap.

Common workarounds:

  • Personal loan during the build, refinance into an RV loan after completion. Pay the builder with a personal loan or cash. Once the build is done and titled as a motorhome, apply for an RV loan and use the proceeds to pay off the personal loan. This works but requires qualifying for two separate loans and managing the transition.
  • Builder payment plan + savings during the build, RV loan at delivery. If the builder accepts milestone payments, use savings during the build period and finance the remaining balance (or the full amount) through an RV loan at delivery.
  • Auto loan for the base vehicle, personal loan for the conversion. The two-loan strategy described in our financing overview.

When an RV Loan Makes Sense for a Conversion

An RV loan is the right tool when:

  • The build is from an RVIA-certified builder (simplest path) — browse our van builder directory to find certified shops
  • The total financed amount is above $50,000 (where the rate difference vs. personal loans matters most)
  • The buyer wants a long repayment term to keep monthly payments manageable
  • The conversion is complete and titled as a motorhome

An RV loan is probably not the right tool when:

  • The builder is not RVIA-certified and the buyer cannot find a lender that will accept the build
  • The financed amount is under $25,000 (below most RV lender minimums)
  • The build is in progress and the buyer needs funds during the build period
  • The buyer’s credit profile would qualify for better personal loan rates than the available RV loan rates

For builds that do not fit the RV loan model, the alternatives are personal loans and financing strategies for non-RVIA builds.
