It says right on the Northstar website:
"The 8.5 Adventurer is 1/2-ton or larger compatible and will fit both long (8') or short bed (6' 6") trucks."
Weight STARTS at 1940 and goes up from there. Typical F150 REAL payload capacities STOP at around 1600 and go DOWN from there. At 1600lbs, the truck is looking SAD in the rear.
What 1/2 ton truck, save for the "fake" 1/2 tons, is going to be able to comfortably haul a camper like this? You're looking at 2500+ by the time all is said and done, 1000+ over your real available payload capacity.
ALL the TC manufacturers do this. How can they in good conscience? Answer is they don't have a conscience. Business is business.
