I've seen a few rigs set up with the truck toppers and a RTT, but are they really supposed to hold and carry that kind of weight? I kinda think i'd like to have one for my Titan but I worry about the structural integrity with it being loaded on top. If it was just myself all the time that would be one thing but not the case.Hello!!
I’m currently looking at truck caps for my 14 GMC Sierra. The end goal is to run our RTT on top, wondering if anybody knows if this Leer cap can handle the weight.

I had a fiberglass Gull Wing Leer on my F150. Mine is not be rated for the weight of two adults.Hello!!

I've owned two fiberglass toppers. Neither of them could carry a load like that. They're just not designed for all of that weight from above...not even close.Hello!!

At a 300 pound load limit, a 200 pound man and a 100 pound woman arrive at the threshold. Now add a 100 + pound RTT and whatever you have up there for gear, and you are likely to find yourself waking up in the bed of the truck some morning, or at least weakening the top and reducing its longevity.I can't tell what model that is, but I looked into weight limits on Leer caps a while back since I have one myself. Wasn't looking to add a RTT, just wanted to know how much I could carry up there (center of gravity concerns aside). Unreinforced fiberglass Leer caps have a limit of 120 lbs (sheer load limit). The reinforced ones have up around 300, from what I recall. Can you load more than that as a static load? Probably. Would I want to risk it? Nope.
If that one is reinforced, and you and the ole lady aren't of the hefty sortm you'd probably be alright with a RTT. If not reinforced, I couldn't recommend it.

The statistics I looked at were shear load limits (I misspelled above). That is the capacity which includes potential horizontal stresses (like you would encounter turning a vehicle at normal driving speeds). Meaning, a reinforced shell with 300 pound capacity could safely support that load not only under stationary conditions, but also with the added g-forces encountered in normal driving conditions. This would logically mean that it would safely hold some higher weight in a static condition, although that is not the basis of their rating.At a 300 pound load limit, a 200 pound man and a 100 pound woman arrive at the threshold. Now add a 100 + pound RTT and whatever you have up there for gear, and you are likely to find yourself waking up in the bed of the truck some morning, or at least weakening the top and reducing its longevity.
I've seen tubular racks with flat mounts that will mount at the stake holes. Put that on, and they are wide enough to fit the cap in between them and rest on the bed rails, so you have some sort of exoskeleton that mounts under the cap, but comes out from under and wraps closely to the shape of the cap and crates a strong roof rack system around and above the cap. Putting an RTT on one of those seems more sensible and robust

Thanks for the info, and that’s a great rig!I have a 130 lbs roofnest on my cap. It's an ARE Z with cross bars. No issues whatsoever.

It is a reinforced contractor cap. I looked into this model and the dynamic load is 400lbs. I know that with us and a bit of gear In it were getting close with a 130lb tent....At a 300 pound load limit, a 200 pound man and a 100 pound woman arrive at the threshold.
