Hi all , thinking about getting a RW 429 toy hauler , i know pretty much zero about 5er hitches , the trailer im looking at has a 21k more ride pin box , i see some hitches have a air bag to make them ride better , does one with the more ride need a air bagged hitch ? I have a 2014 dodge dueley 1 ton mega cab , also have a aux fuel tank in the bed , sticks back into the bed about 20 inches , what would be a good hitch for my setup ? any and all ideas welcome , thanks in advance !
