Roof rack & RTT = bent roof/gutters?

First, I have read a great number of posts (like this) on the issue, but there are few consistent answers out there and none that I have seen that would lead me to expect what I now see on my rig.
I put a Big Country rack on my 90 about a year ago and popped a 165lb RTT on top. Camping trips all over in the year since. 400lbs of additional human weight in there in the evenings.
I started to notice rubbing of the top of my door on the rack mount that clips under the gutter immediately and shifted my door down a bit. Also took off the thin rubber pad on this L bracket to have it fit tighter to the gutter. It now only extends ~3mm below the gutter.
On my last trip, after getting in, I found myself trapped in the driver seat and really having to shoulder my way out of the truck. Bracket had to be removed.
Got home and pulled all driver side brackets and checked gutter along length of the drivers side with a straight edge (aluminum bar in photo below). Sure enough I have a good dip in my roof (at the gutter) as you can see from the departure of the straight edge as it approaches the front of the truck (when aligned with the gutter at the rear).

  1. Anything I can do to get my roof 'back in line'?
  2. I'm guessing my roof is not suitable and will switch the tent to either our new 110 or my wife's D2, but am curious whether this is a unique outcome or if I'm missing some support/bracing inside or have my rack feet in a poor spot. Just not sure why others don't seem to have the trouble I have had.
Thoughts/insight appreciated.

I wouldn't give up. I would move the front leg as far forward as possible and put another one right behind the door jam.

Or spend the money to add a cage and then mount to the cage.

You can probably get your roof back in line relatively easy with a floor jack and a long piece of wood.

I think there is also an internal seat belt mount that goes from the roof line to the belt rail that is made of steel may want to look into that.

I'm with Naplm00 on this one. More feet to distribute the load, and perhaps some different placement to where there is more direct support. The latter won't make much difference if the deformation is in the gutter itself.

Don't forget that your 400lb of humans is static weight. As you're climbing in, moving about, and turning over you're creating dynamic loads that are unlikely to be evenly distributed.

Mine is a 110, but I have 4 cross bars but they are a little offset the the rear to hold the RTT. Mine is the big Thule one so it's #200.
My attachments in the gutter might be a little wider than yours, not sure if that extra inch is that big of a deal, but I guess it could spread the weight by an additional 20%, so maybe.
I'd hope if you got one more cross bar you'd be good.

My rack is a custom 4x9 square tubing and I did break a weld after nine days and 1,600 miles due to the extra leverage of the RTT open off the back. I added one more cross brace which may have changed the weight distribution on the attachments too.
