Front Runner Load Bars w/ RTT?

I’ve seen this done before but I’ve also read some conflicting opinions. Will the tracks on the bed sides hold up using this system with an iKamper Mini and two average adults? The bars don’t have a lip using the top of bed for support like most racks. The tracks I believe will hold 440lbs each is what I read.

Here’s a link to the actual product:

I use 2 of the front runner load bars with a tepui rtt and total chaos bed stiffeners. My wife and I in the tent. No issues haven’t seen any bed deflection or signs of stress on the rails.

 

Thanks for the response.

Front Runner said I would be fine so I'm sticking with it. Only got 4-5 weeks until my iKamper arrives!

 

I have 3 Front Runner bars (got off Craigslist fo$75) but mine are mounted on extensions that I had made. No issues with my 120 lb RTT and me and the wife up there.
