Thank you so much for yall's input!! I got email back from Oliver and it said "The GVWR is pretty much the rating of the axles. They are rated to 7,000lbs. Your are correct, the dry weight is 4,900lbs. The heaviest we have gotten a trailer to is 5,600lbs. That is with tanks full and 500lbs of camping gear. If a Ranger will tow 7,500lbs, you should be fine with one of our trailers. We recommend a vehicle with at least 7,000lbs capacity. You should be fine with a Ford Ranger. "
I am hearing you all about the gas tank size and payload capacity. I looked up a Tacoma and it is rated up to 6800 lbs towing and the payload is 1,050 to 1,685 lbs. The Ranger is up to 7500 lbs towing and its payload is 1609 to 1905 lbs. I would love to be able to get the F150 hybrid with generator but its so expensive. And if the Ranger will do it for now.....I can always upgrade to the 150 later, right??
