Recommend TC??

What's important to you floorplan wise? What's your budget? Do you want a slide? Do you boondock or stay in campgrounds because that will make things like tank size or solar/generator options more or less important.

Adventurer makes several nice mid size campers, Wolf Creek has the 840 and 850. Lance has several mid size units. Arctic Fox has the limited run 865 available right now (don't look for it on their website).

put 19'5 wheels and commercial tires rated at 4850# each then keep the rear axle scale weight under 8000 loaded and you should be good to go towing the boat too with most single slide TC's

Beefy anti-sway bars too are a must
