All good advise here.
A TT wil respond quicker and will travel backwards easier than a 5er. I have been popup, TT and now a 5er.
The PU was easy like utility trailer. the TT was a learning curve, but once I had it, it was easy to back about anywhere as long as you had room on the front side of truck.
BUT the 5er well lets says that almost 5 years later we still have a curve to learn.
MY best advise is practice practice with either in a school parking lot with some traffic cones on the weekends.
BUT I can get the 5er about anywhere i want but I have to say out loud.. SLOW and EASY.. I have to keep repeteing this statement o remind myself SLOW and EASY. small corrections move the 5er a lot. I back into my parking spot at home from the blind side as they say. SO I have mailbox at the road and a ditch on both sides and then I thread the needle to get it into a 14' wide parking spot. Sometimes I have to pull out and go around the block and try it again.. These are times i am tired from driving home from a trip and I get in a hurry, I forget the SLOW and EASY phrase and I get upset and try again. I will be honest I thought I would never get it. BUT each trip it seems to get easier but i still go SLOW and EASY backing it.. Last trip out I had to back into a camping spot as their drive thru's were filled up. I was worried the whole ride to the campground, then on the money first try.
BUT again Slow and Easy backing...
best of luck,
JMHO,
