"Now my question: Is there a difference in the ability to drive backwards with a normal trailer compared to a 5th wheel trailer?
"In total a 24" trailer + car might be a few feet longer than a
24" 5th wheel on a Pickup Truck (I would say 4-6 feet at least?)
So if there is a trailer limit of 24", would you say that you can still get into that campsite with a (example) 26" 5th wheel? Or doesn't it make any difference when trying to get into a spot? "
Our previous RV was a 32" TT. Our current is a 35" 5" fifth wheel. We have found that we can get into the same spots that we fit the TT. When you say drive backwards, I'm assuming backing up. There is a difference in TT vs FW because a FW is much more responsive. You're right about roads in and turns. We've found CG's with great sites, but forget about getting in. What I do often, is to check out Google Maps and I use the measurement scale at the bottom of the screen to measure the site and use other RV's seen as a comparison.
As stated by one other person here, we haven't found any problems with SP's, but NP are different. They built their campgrounds back before all these modern RV's and those can be a problem, but not inpossible with a shorter FW or TT.
