Re: Towing newbe with question about controller relay & trailer.
By relay I am assuming you are asking about the charge line. The tow package has a 7 prong Bargeman style plug, 6 contacts around the outside and center pin. Turn your ignition to on, and with a DC tester or multimeter check for current on the center pin that is the charge circuit.
272TBS probably is 27' but the model number is NOT always the actual size. Go to Coachmans web site and look at the specs for that model number.
Yes you do want a WDH and sway control. Air bags are a nice addition if you don't mind the cost. NEVER load up the rear of the rig just to just to get weight off the hitch. This causes dangerous sway when you get up to speed.
Hope this helps.
