Since you seem to like Thor products, look very seriousily at the Heartland 5th wheels!
Many have 88% turning radius front caps..which mean easier and safer turning up to 88 degrees
without a slider hitch. Heartland is the 3rd largest manufacturer and 3rd in sales of 5th wheel RV's. They are remarkable in the Thor RV ownes Heartland, but Thor leaves Heartlands Management team completely alone to continue their remarkable growth due to high quality, a commitment to their customers and a very talented management team and work force.
And that's very high praise from me...I'm a rabid Jayco fan!

Truck bed size-In day to day driving there is little perceived difference between 6'5" and 8' bed trucks.
Backing that big girl up in a WalMart Parking lot, easing into a parking space or thru a McDonalds Drive Thru can be almost docking a ship!
The advantages in Long Beds are a bigger fuel tank, better ride due to longer wheel base, cargo room in the bed even when towing, long bed can swallow a standard sheet of plywood/drywall, and much more..full sized truck campers will fit for example.
BUT 6.5 foot trucks resale better, outsell long beds by 10 to 1, are more popular, easier to park and manuever, and less intimiidating to some drivers.
Good luck!
