NBS vs. OBS

[pondsy]

I tow a fifth wheel with 7" clearance to the bed rail on my 06 LLY 2500 standard bed.

I know the NBS has a higher rail.

Questions:

What will I loose in clearance going to the NBS?

A Retrax cover sits about 1/2 above the rail - add that to the extra height of the NBS bed rails and will have a problem?

I do tow my camper off road a little (nothing major, but there can be a bit of torque from side to side (hitch has 4" side to side play).

Should I stay away from the Retrax?

TIA and Merry Christmas.

I'm trying to remember, my dad and I measured the bed depth from our identical 1/2" rubber mats up to the top and I think his is only 1" or so deeper. The bedsides LOOK a lot deeper, but in actuality aren't that much.

Based on that, it'll be about an inch and a half difference in height. That would give me 5 1/2 inches of clearance.

Since my hitch will only go 4 inches either way - It'll be close, but I think I'll be OK.

Thanks Devin.
