An SUV is too generic, so are you towing with a volvo c90 or A GMC Yukon XL ? The issue will be tongue weight and payload on the suv. Keep in mind the payload includes, people, fuel and other cargo carried inside the vehicle.
I agree with the above post, short wheel base and 30 foot tt is a recipe for disaster especially in windy conditions or a poorly loaded trailer.
So the yukon xl or suburban has a max payload of 1800 pounds, with a 900 pound tongue weigh, 30 gallons of fuel, 2 people you will have ballpark 400 pounds of payload left.
reread the post......saw the lexus gx mentioned. the max payload is 1470 pounds. which is not enough for the trailer you are looking at. Plus it would be miserable in the mountains or in any cross wind.
Max-tongue weight-fuel-people= too much, especially with nothing else in the suv
1470-900-200-300=1400
