we bought an Outback 315 fre fifth wheel (10,475 GVWR) as far as the weight ratings go, right at 9000 lbs according to sticker with full water and empty waste. truck squatted less than half an inch I think, she said it didnt' move when we set the trailer on the truck. I will get home, empty all, get r weighed, then weigh again with normal loaded food, clothes and toys! ! ! Pulls just like the trailer, only lost about 1/2 MPG at this point, rpms are just about the same and so it must be mostly pushing the extra height of. wind. Seems like the only weeving is when a truck passes and gets in fornt of us and I get stuck in his whipping tale wind for a moment, just a little wobble. Other than that all is good and I am 99% sure all the weights are fine.
