I'm new to the t trailer world, my wife and I own a 07 Chevy duramax new body style with 6.5 foot bed. And are going too buy, a 2006 34 ft cougar fifth wheel. any ideas on sliding hitch that would work well with that combination. I have a concern about the bed on the truck, on the new body style Chevy's the beds are 2inches deeper than the older ones. thank you very much lm looking for constructive advice
