The bolts just need to be 'snug'-------something like 40-50 INCH lbs.
The roof gasket is roughly 1" thick and gets compressed to 1/2" thick.
If you compress it more than that it can warp and not seal between bottom A/C pan and roof opening. The gasket is all that seals the unit.
Under the shroud is another cover that encloses the evap coil. If that cover is not properly sealed water can get into that area which is open to the inside of rig.
