2100 keystone cabana no sway or load leveling do i need it?

I have had many tv's in my 70 some years and I have to say, never ask a small boy to do a man's job. with out the tranny cooler he will be looking at putting a new tranny in sooner or later. with that cost in mind he might as well buy a truck that can do the job in the first place. he will be putting in more money than the truck he has is worth trying to get it up to a good towing capabilty.. which is not a good idea, just take the money he is going to spend on this truck and get a TRUCK
