Good morning....
A couple of comments.
1. We had a TT previously with the bi-fold stove top. The Outback 5er, not so. Bought a non skid "board" top; comes in black or butcher block grain from RV World. WORKS GREAT....no skid. Towed 700 miles and never moved one inch. About $40... When stationary, you can stow as you would on the bi-fold.
2. I did not "drop" my 5er into the truck bed, BUT, on my first trip out, even with the new style front cap, I "forgot" to leave my tail gate down when backing with the slider in the "manuver" position and bingo dent on top of the gate
After much chagrin; I found an inexpensive fix that made me OK again.... 3 lessons learned from this experience for me personally:
1. Make sure you have clearance
2. Take your your time backing and check frequently
3. Only "listen" to others comments and DO WHAT YOUR INSTINCTS tell you.
For me; I was really, really not as well informed as I should have made myself before the trip. I am now !! Heading soon for the Daytona 500 and then on to Bike Week...no future bumps planned at this time !
