I think there are other considerations, Being the tow guy for my Salty boat buddies I've towed a couple of boats about 30' counting the entire trailer and backing up a long bumper pulled trailer is fairly straight forward but looking at the main differences, pulled from bumper or from over the axle, I think they will react differently no matter what.
When the bumper pull follows you the bumper is leading, when I tow the 5er the point becomes closer to the cab over the axle and when I pull out I have to square off corners in order to make the corner.
I think the two styles might require a slightly different footprint (or tire print) to accomplish the same move.
I want to think my 5er axles will tear up the grass on the corners more so than a bumper pull rig if I were to steer out the same attitude.
Am I dreaming or could this be a factor in what the CC said about TT vs. FW in a particular site on their premises?
I'm also a big fan of checking out the site from space to help in choosing a site.
