We are with AllState and have everything insured though them.
We do have a house and pay for a separate policy there.
And we have the automobile policies with the Montana Fifth Wheel as a rider on it. The cost for the fifth wheel is $402.73 every 6 months, or $805.56 a year, or 67.13 a month.
BUT: we have 2 pick-up trucks insured, (the dually and a Chevy Colorado) also, and all are full coverage insured for everything and anything.... total cost $2212.87 every 6 months (or $4425.74 a year) ... YIKES!
Now, we are NOT declared "full timers" and we still own our house.
But, between the house and car / camper insurance we are covered for all of the following:
While towing the trailer:
Anything that happens to the trailer or if the trailer is the cause of someone else's damage, if it's my fault or the other guy. (uninsured motorist also).
When not towing:
Anything that happens (or damages) to the trailer, if it be my fault or a fault of nature. (flooding, tree falling, tornado, fire, theft, vandalism, or my own negligence)
(it does not cover normal wear and tear, like broken slide cables or worn tires, or outdated propane tanks).
There is one more area of coverage that we have, because we have a house. We have personal liability insurance also... (with the house insurance) ....
What that covers is: If our dog bites someone; and if someone has an accident at our campsite or inside the camper and it can be determined their accident was a result of something I was negligent in doing (not the campgrounds fault). And personal items against theft. For example, if someone stole this lap-top computer I'm typing from right now, at home, in the camper, or in the car, it's covered for replacement. Anything in the camper that could be stolen is covered under the home-owners. It's not part of the trailer coverage.
We also have the vanishing deductible, which at current is a zero deductible.
Of course, "insurance" of any type is a gamble. The insurance company is gambling you won't need a pay-out, and you are gambling sometime you will. We've used insurance for any campers we've owned, only once, and that more than 25 years ago. But, I don't feel bad about paying for it all these years and never having to make a claim. It takes only 1 time and your entire life can be undone if you don't have insurance.
