To add to what has been said closely inspect all rubber seals, especially those around the slides. Rubber and FL do not play well together. If the unit has not been used the seals may not have been maintained and may be ready to fail. Not cheap. No idea how much as type and length play a large role in determining that.
Any other rubber parts, belts, etc should be inspected before driving home. They are much less expensive to repair in the yard than on the side of the road.
Coach-net has my vote, I'm partial, I have had them since 2001 and like the way they respond, mostly..
Insurance is a cr-p shoot. I am happy with Progressive, never had a problem with GM would insist on a company that offers a fulltimer rider. If they don't acknowledge full time and you do have a claim they have a legit excuse to terminate your policy and NOT pay.
Stopping, let someone else write the book.
