I have some 'elderly' neighbors that are probably in their 80's now.. Been our neighbors (at the end of our street) since we moved into our house 15 years ago.
15 years ago, they had about a 30' TT pulled with a Chevy crew cab dually.
Couple of years later, they got about the same length 5th wheel towed with the same dually.
Couple more years later, they got a Class A. Towed their new Chevy Colorado behind it.
Couple of years later, they got a Class C. Still towed the Colorado behind it.
Couple of years later, they got a Class B. Still towed the Colorado behind it.
Well, last year, while towing the Colorado, it caught on fire! They have no idea how it occured, just that it burned to the ground and melted the back of the Class B a little bit..
Today, they have a brand new 1500 Chevy Silverado and are towing a 25' TT...
For the last 12 years I've been towing the same 22' TT with the same 1997 F150.. :)
Anyway, I can't really help you with what to do, but I do know that the next RV I would like to get if I had the means will be a Class A.. :)
Good luck!
Mitch
