Newbie to travel trailers- need advice on selection

That would work but the tongue weight would be a problem on the Jeep. What these guys are recommending initially is a lighter duty friction type for the Jeep that can also be used on the 4Runner but I wold have to careful with how much I load the trailer storage area in front. So, I have to make a decision on this. They say if they use the 600lb one, they have seen it do damage on Jeep frames and lighter vehicles due to the lighter tongue weight capacity of the vehicle.
