KMs.......We run them so long cause they will and every fall almost have a line up to buy the old out going ones. A hwy tractor seems little over kill to haul a not to mention if the work to moving the back axle to the front loping off the rear of the frame and getting it re-saftied. And just the sheer size of it to get it into a campground....pulling it would not be an issue a 17,000 would hardly know it's there.
Myself I would got for something more like this...already to go
