This is what I did, not insurance advice. Coverage, rules, and pricing vary by state, insurer, and your own record. Use this to know what questions to ask, then call your own agent.
Do you even need to insure a truck camper?
No state legally requires it. A slide-in like the M1 isn't titled or registered the way a travel trailer is, so nobody's going to stop you from running it bare. But "not required" and "not a good idea" are different things. Your truck's auto policy treats the camper as cargo at best, which usually means it won't pay out anything close to the camper's real value if it's stolen off the truck or crushed in a rollover. On a $16,000 build, that gap is the whole reason to bother.
How does a truck camper actually get insured?
Two paths. The first is leaning on your auto policy and hoping its cargo or personal-property terms cover the camper. They rarely cover the full value, and that's where people get burned. The second is a dedicated RV or truck-camper policy that covers the camper itself: comprehensive, collision, total-loss value, and the gear inside. That's the path I took.
The M1 is a weird case for insurers because it's permanent-ish but not a titled RV, so you're insuring a stated value rather than a VIN. That turns out to matter a lot for the next part.
Replacement value, not depreciated cash value
This is the part I'd tell every M1 owner to get right. When a camper is totaled, an insurer can pay you one of two ways. Actual cash value pays what the thing is worth today, after depreciation, which on anything a few years old is a gut-punch. Replacement or agreed value pays to replace it or pays the amount you insured it for, with no depreciation haircut.
You want the second one. And here's the trap: some mainstream insurers under-value a custom camper when you call, because their system doesn't know what an M1 is. I found other truck-camper owners who got quoted a "total value" far below their build and had to move to an RV specialist like Roamly to get true agreed value. The number on your policy is only as good as the value you fight to get on it.
What I actually did
I insured the M1 with Progressive at a stated value of $16,000, on Total Loss Replacement coverage. Because the camper is new (Progressive's replacement benefit runs for the first five model years), a total loss means they put me in a brand-new equivalent, or cut me the original purchase price if I don't replace it, minus my deductible. After five years it settles to the $16,000 I specified. Either way it isn't a depreciated payout, which was the whole point.
Comprehensive is on there with a $1,000 deductible, and my policy drops that to $750 after a claim-free first year on both the total-loss and comprehensive side. That's how mine is written, so ask about it rather than assuming it's standard.
Here's the policy at a glance:
| Coverage | What I have |
|---|---|
| Insurer | Progressive (bundled with my truck) |
| Insured value | $16,000, Total Loss Replacement |
| Comprehensive deductible | $1,000, drops to $750 after a claim-free year |
| Contents (personal effects) | Up to $5,000 |
| Term | 1 year |
| Premium | $347/year (about $29/month) |
Why Progressive? Honestly, I didn't shop it to exhaustion. My truck was already there, they're a major RV insurer, and the bundled price was fair. If you've got a highly custom or higher-value build, get a second quote from an agreed-value specialist before you sign, because the value they'll write is the part that varies most. About $29 a month to protect $16,000 of camper did more to talk me out of skipping coverage than any sales pitch could.
What about the gear inside?
Two layers, and most people only know about one. My camper policy includes Replacement Cost / Personal Effects coverage up to $5,000 for the stuff inside, which a lot of owners don't realize their RV policy even carries. Check your own policy's contents limit first.
Beyond that, or for broader coverage of your personal property, a renters or homeowners policy is the second layer (my household's renters covers the overflow). The camper policy protects the shell and a set amount of contents. Anything past that limit is on your personal-property coverage, not the camper policy.
Comprehensive is your theft and weather coverage
The coverage doing the quiet work here is comprehensive. It's what pays out when the camper is parked and something happens to it: theft, a break-in, vandalism, hail, a tree limb, an animal. For a truck camper that spends most of its life sitting on the truck in a driveway or at a trailhead, that's the real risk profile, not a highway collision.
It's also why the tailgate matters. The tailgate is the door to everything stored in the bed under the camper, and comprehensive is what backstops a theft. Insurance is the fallback, though, not the lock, so hardening the tailgate itself is a separate job worth doing.
The questions to ask your agent
- Am I getting replacement/agreed value, or actual cash value?
- What exact dollar amount is on the policy, and does it match what I paid?
- Comprehensive and collision both, and what are the deductibles?
- Does the deductible drop over time if I stay claim-free?
- What's the contents limit, and do I need renters on top of it?
- Am I covered for liability while driving with the camper on?
- Is there a multi-policy discount if I bundle with my truck?
- Any usage limits, like recreational versus full-time living?
My take
Get replacement value, confirm the dollar amount actually matches your build, bundle it, and add renters if your gear runs past the camper policy's contents limit. The $16,000 number on the policy is only real if the fine print pays it. Mine costs $347 a year, and for a camper I can't easily replace, that was the easiest yes on the whole build. If you're still working out what's going on the truck, run your setup through the payload calculator first, and here's the full breakdown of what I ordered and paid, insurance included.
