Shift happens

[Tetonchief]

I have a Canyon Star 3856. I have slowly began moving into it these past few days--going full time Dec 1. For the time being (until I figure it all out) I went to put 3 ammo cans (plastic plano boxes) into my basement compartment and was taken aback by the apparent sag from the weight of the ammo cans (they are full of 9mm, 45, and 5.56) and each weighs about 20-25 lb. I spread them out about 2 feet between but then took them out and put them in the shed until I figure this out. I know on aircraft the overheads have a max weight from 40 -75 lbs (depending on size). The surprise from the sag is because I didn't anticipate the basement floor to be so thin (the PO put a quarter inch lining of rubber flooring which makes it nice). Does anyone have an idea what the weight limits of the compartments and floor is? Or somewhere I would find this info. Thanks.

I have a heavy tool box because of weight to one side of a lower compartment.
The upper floor of compartment is set on the chassis rails to hold heaver weight you would need to disperse in different compartments to level off your load for weight your adding.
You could have a welder place bracing under compartment floor outside to support the heavy items but weight in all same compartment may imbalance your coach.
