Last December in Ferndale, CA I saw a cabover diesel tractor with about a 16 ft travel trailer sitting up on the frame behind the cab. It was a retired AF Officers travel home. I wish I had taken a picture.
Heck Yeah!!! I have a friend who bought a Freightliner and pulled a 5th wheel around the country. The truck handled the job easily whereas the HD Pickups would struggle pretty hard with his use. He and his wife are retired in Arizona, but were from Michigan originally, they like to travel to Alaska and the the USA.
They live in Arizona during the Winter months.
I was gonna get the biggest engined V12, Cat or Detroit Diesel, over the road tractor, Peterbilt, Kenworth etc., and put a pickup box where the 5th whjeel would be, for my personal town carriage. It would've made quite a show, lights and noise and smoke! *** BLESS AMERICA!!!
