All this talk about flat towing makes me want to ask. Mike that type setup on a big coach like yours. Can you back up? Reason I ask is being the VW person I am I have flat towed many with the standard ole VW tow bar sold every where. And those well backing up Nope.
I warn customers every time I sell one and some don't listen
JC, no ability to back up when flat towing like this. You have to pick your fuel stops and turns carefully which is one con to flat-towing vs. towing a trailer.
I hear all the time about people who have bent their tow bars because they backed up and thought because it was such a short distance that they would be fine. The stresses put on the tow-bar when those front wheels all of a sudden turn due to the opposite caster when backing is tremendous and it will twist a tow bar into a pretzel very quick. Sitting behind the wheel of a 30k-50k pound coach you won't even feel it until it's too late. That being said, in the 100k plus miles I have flat-towed Jeeps over the past 20+ years I have only had to unhook twice because I couldn't back up.
Once was because I took the wrong turn into a campground in Grand Junction, CO. The sign said turn right so I immediately turned right where I turned into a cul-de-sac and couldn't make the turn with our last coach. Had to disconnect and back the coach out of the cul-de-sac. Luckily I only had to go to the next driveway so I just had the wife follow me in the Jeep right next door. I inquired at the office and they told me that the neighborhood just went in that summer and they should probably move their sign as that is quite common.

REALLY? If that is common, move the stinking sign, pretty simple.
The other time was at a small fuel station in Monticello, UT. I had pulled in to fuel up at a fuel station I had used in the past and knew I could drive around the building upon exiting. While I was fueling the fuel delivery truck pulled in and commenced stringing hoses and filling the tanks.

This time I had to disconnect the Jeep, have the wife drive it across the road while I backed the coach out then drove about a quarter mile down the road to reconnect the Jeep and were on our way again. Not the end of the world but something that wasn't planned.
All in all I feel pretty good in all those miles to have only had to disconnect a couple of times.
Had I been towing the trailer I could have backed out of the fuel station pretty easily but the cul-de-sac would have been a bit more problematic due to the busy street I would have been backing out onto.
Once when we were towing the trailer we took a turn in Winnemucca, NV and after driving down it for almost a half a mile found out they had it blocked off doing construction. Luckily I radio'd back to the other members of our party not to come down the road so the other three rigs pulled off but I had to back up more than a quarter of a mile @ 72' long coach and trailer until I found a wide enough spot in the road where I could do a three-point turn. Luckily I can back well, other members of our party would not have faired as well.
