I need to get a fifth wheel hitch i have a 2007.5 2500 cc short box LLM on the way I have never had a fifth wheel hitch and need some info on what kind of hitch i should buy. I assume that i will need a slider with short box but is it nessasary to get a fully automatic one or can i make do with a manual slider? I really dont want to drop $2k for a hitch. But if it is going to save me from damaging my truck i will. Just wanted some feed back from some people that have experience with different kinds of hitches. Any advice would be appreciated.
