We insured our A126 with progressive as USAA doesn't write camper/motorbike policies. They have a partnership with progressive for those needs. Comp Collision and loss of use liability and replacement cost coverage with $1000 personal item protection run us $109 a year.
USAA extends all of my coverage to the camper while towing.
Our progressive has the vanishing deductibles as well, and replacement cost is one year newer camper for first 5 years and original purchase price after that, with no depreciation. They also offer acv less salvage coverages but at only $109 I didn't see any point.
