Allstate Van Conversion Insurance: What's Behind the RV Quote
Allstate RV quotes redirect to National General, an Allstate subsidiary. What that means for van conversion coverage and when it's worth trying.
Allstate does not directly write van conversion insurance policies. When you click “get a quote” on Allstate’s RV insurance page, the request redirects to National General — an Allstate subsidiary since January 2021 ($4 billion acquisition). National General is also the underwriter behind Good Sam RV insurance.
This creates an unusual situation: if you are shopping for van conversion insurance through Allstate, you are functionally shopping for a National General policy. And if you are also considering Good Sam, you may be comparing two products written by the same underwriter under different brand names. For context on how Allstate fits within the broader landscape, see the camper van insurance overview.
How the Allstate → National General Pipeline Works
Allstate’s RV insurance page lists coverage for Class A, B, and C motorhomes, travel trailers, fifth-wheels, pop-up campers, and toy haulers. There is no mention of van conversions, DIY builds, or modified vehicles anywhere on the page.
When you request a quote, the process routes to National General. This means the underwriting criteria for van conversions through Allstate are the same as the criteria documented in National General’s Countrywide RV Underwriting Guide:
- All seven habitation features must be permanently installed (cooking, refrigeration, sleeping, bathroom with indoor plumbing, HVAC, potable water, 110-125V electrical)
- Photos required upfront
- Builds with settlement value at or above $50,000 are referred to underwriting
- Agreed Value capped at $300,000 for customized units without Blue Book comparables
- Class B van conversions are not available in California
If you meet these requirements, a quote through Allstate will produce a National General policy. If you do not meet them — for example, if your build does not have indoor plumbing or a toilet — the quote will be declined regardless of whether you called it “Allstate” or “Good Sam.”
What Owners Report
Owner reports on Allstate for van conversions are mixed, which is consistent with what you would expect from a product that is ultimately agent-dependent on the front end but standardized on the back end.
On the Ram ProMaster Forum, one owner reported switching from Progressive Commercial ($1,546/year full coverage) to Allstate at approximately $558/year for full coverage as an RV. Allstate told the owner they could insure the ProMaster as an RV while it was still registered as a cargo van. This suggests some Allstate agents can access the National General RV product and apply it to converted vans, even without retitling — though this appears to be agent-dependent.
In a separate ProMaster Forum thread, a Michigan owner added a converted van to Allstate as a personal vehicle without difficulty. Another owner used Allstate’s “Milewise” (pay-per-mile) product during the build phase — a creative workaround for keeping premiums low on a vehicle that is not being driven regularly during conversion.
Contradicting these reports, other sources indicate that Allstate — in some regions — requires conversions to be done by professional, established van building companies and will not cover DIY builds. The pattern appears to be location-dependent and agent-dependent, similar to State Farm but with less flexibility, since the underlying product is ultimately National General’s standardized RV underwriting.
Allstate vs. Good Sam: Same Underwriter, Different Experience
Since both Allstate and Good Sam route to National General, the coverage product is the same. The differences are in the front-end experience:
| Factor | Allstate | Good Sam |
|---|---|---|
| Underwriter | National General | National General |
| Quote process | Allstate agent or website → National General | Good Sam website or phone → National General |
| Agent relationship | Local Allstate agent | Good Sam Insurance Agency (phone-based) |
| Multi-policy discount | Yes (Allstate auto + home) | No (Good Sam is standalone) |
| Good Sam membership required | No | No (but membership adds roadside and other benefits) |
| DIY build acceptance | Agent-dependent | Consistent (if you meet the 7-feature requirement) |
If you already have Allstate for auto and home insurance, quoting through Allstate may produce a lower total premium due to multi-policy bundling. If you do not have an existing Allstate relationship, quoting through Good Sam directly is more straightforward — the product is the same, and Good Sam’s phone-based agents are specifically trained on RV products.
Where Allstate Fits
Allstate is worth trying when:
- You already carry Allstate auto and/or home insurance and want the multi-policy discount
- Your build meets all seven National General habitation requirements (cooking, fridge, sleeping, bathroom with indoor plumbing, HVAC, water, electrical)
- You are not in California (National General does not write Class B policies in CA)
Allstate is the wrong call when:
- Your build does not meet the seven-feature requirement — the National General underwriting will decline it regardless of the Allstate branding
- You have a DIY build in a region where Allstate agents are requiring professional conversions only
- You need agreed value above $300,000
Better alternatives for DIY van conversions:
- Roamly — Purpose-built for DIY conversions. Does not require all seven habitation features.
- Progressive — Covers DIY van conversions since November 2023. Requires six habitation features (no toilet or indoor plumbing required).
- State Farm — Agent-dependent, but the most flexible criteria among major carriers (4 of 6 habitation features).
