Have you considered possibly purchasing a used Class C? Your truck is already 7 years old with how many miles? A TT is going to put a lot of wear and tear on it and if it's your primary mode of transportation when not camping, wouldn't you be better off with something, that if you have a problem, won't affect your day to day activities? Last year we found our 2000 Georgie Boy 31ft Maverick "C" at a local dealer. It's built on the E450 Super Duty chassis with the Ford V10. Had 26,000 miles on it, 100 hours on the genset, the roof had been redone within the previous year, awning looks like it had never seen the light of day, interior is extremely clean and wear and tear free. It has no slides which is OK for me as I feel that affects your overall weight towing and carrying capacity. Out the door was 16K. The unit drives great and handles the mountains here with no problems. Tows our trailer with our 2 ATVs without breaking a sweat. AND, if we have a problem with it, we still have our other 3 vehicles to use, so our daily activities are not affected at all.
