Just got A Wolfpack M-27DFWP So confused Got it so we could haul our street bikes. I was pulling a 5th wheel I am so confused on towing a tow behind TT it looks like it is so much harder then a fifth wheel. Purchased the unit used, first ??? does any one know any thing about getting the remote for the ZX75 to work? I already replaced the battery but that did not work. Also does any one know what the M stands for on the model? I do not have any manuals with the unit is there some where I can get them?
