Hello all, I'm a new comer to the RV'ing world. Just bought a 29' Cougar 5th wheel. It does have the extended pin box, I drive a full size Toyota Tundra with a 6.5' bed. The RV salesman tell me that I will need a slider hitch and they want to charge me like $1400.00 to install one. I've talked to a couple of parts guys at the dealerships and they say that I really don't need one. But I am concerened with cutting a corner sharp to manuver and getting my rear window into the corner of the 5th wheel? I haven't actually installed any hitch yet. Anyone have an opinion on this?
