If you only have 5" between the front of the trailer and bed rails, then increase it by 1" to 2" and you will be fine.
Your center of gravity is actually pretty low, and you can 'tip' it a lot before it will roll over at low speeds. Yet it is much easier to roll over a fifth wheel by slowing the truck and making a sharp turn. I saw at least 3 big rigs that rolled over at the onramp in the Long Beach Harbor. What happens is the truck driver is speeding up to make the green arrow light, but as they go around the curve, they slow down, downshift, and the trailer is still moving say 18 MPH, but the truck is starting to go sideways and slowing to say 15 MPH, and the trailer pushes forward, but the truck is 20% to the left, and it goes over. You can try this with a kid's pickup and trailer, or a child's tractor and fifth wheel, and you will see if you push the trailer forward while steering sharp turn, the kid's tractor will also buckle under and tip over.
Usually this is not the case in a RV and pickup. With electric brakes, the trailer is slowed down correctly into the turn, and your pickup will not have nearly as much slowing ability as a big rig's 12 liter engine when downshifting.
Have fun camping!

Money can't buy happiness but somehow it's more comfortable to cry in a
Porsche or Country Coach!
If there's a WILL, I want to be in it!
I havn't been everywhere, but it's on my list.
