I agree with a previous poster - If you're going to tow with a dolly, you really need to have a hitch receiver installed on your toad, to allow you to move the dolly easier. There's several different circumstances that can come up, where being able to move the dolly easily with the toad will be a life (and back!) saver.
Although we now tow 4 down, we got into a similar predicament at a gas station a few months ago. Pulled in, fueled up, thought there was enough room in back of gas station to turn rig around and leave. Sooo, when we left, I went back there, planning to swing a big U turn and go out same way I came in.
Well, I kinda miscalculated, and when swinging around the turn, got to the point where MH could go no further without right front tire climbing a huge curb. Was 'bout to unhitch the toad and re-position, when I got brave (stupid maybe?) and realized that I was on a gravel/dirt parking lot, and tires should be able to 'slide' some without hurting anything. Sooo, I shifted MH into reverse, and started veeerry slowly and gently backing, even though toad and MH were alread at a pretty sharp angle.
I know, I know, crazy idea, will tear up the toad and tow bar, blah blah blah. Well, it didn't. Since I was on gravel, backing up just caused MH to 'push' the front of toad sideways a little bit. DW was out watching toad and tow bar closely, said it made no horrible noises, none of that. Front wheels of toad just skidded sideways on the gravel a little as I backed up.
Anyway, I only backed up less than a foot, just enough so I could come back forward and front wheel of MH would clear the huge curb and we were on our way. It worked! Inspected the tow bar and toad real closely after that, did not see where it had hurt a thing.
Lesson learned from that: Sometimes slicker surfaces like gravel or dirt can actually be your friend, haha. No doubt it would have been safer and less risky to de-toad/unhitch, but backing up in this situation worked OK. Never would have tried that if we were on hard pavement, though.
