We got our first fifth wheel last fall and struggle (putting it mildly) with connecting. We have a Ford F250 with the factory installed connections for the Reese hitch. We have a short bed with the manual slider which was only one available last year.
Hooking up: we can only seem to get connected when backing straight back with no angle whatsoever. Fine where we store it but some campgrounds are so tight it is virtually impossible to do. I have watched others come in at an angle which also makes pulling out easier.
Unhooking: we let the front legs down (hydraulic) till they just touch and then search for the one position when the lever will release. Again I must be almost perfectly straight to be able to get lever to release.
Slider: We rarely use it because nose of camper is rounded and won't hit but unless I can get perfectly straight the tailgate won't go down unless we slide it back. Once we slide it back we have no luck getting it back to tow position unless we take the weight off with the front supports.
I have read the manual that came with hitch so much I have it memorized. We know there must be something we are missing but not sure what. In June we go to the beach for two weeks and know the site we have will not allow us to pull straight out to unhook. Any suggestions would be appreciated. Going to try and find someplace to get lessons but no luck so far. Dealer sets on perfectly level blacktop so stuff works nice there. They gave us the basic 5 minute this is how demo when we picked it up but it all seemed so simple then. May try and bribe the sales demo guy with a real nice steak dinner for a little more in depth training
