How much weight can the basement compartments hold?
My experience with the 2860 has been
"not a problem"
Because none of the bays are "big"
The rear pass through is so shallow and the other ones small I just can't seem to get enough stuff in any one compartment to over load.
I do like the fact that I've been able to designate individual bays for specific items
ie. tools/parts lower right of front door
Motorcycle gear where the water pump is accessed
All fresh water and hoses/slinky tower
Left side forward
Patio rug behind that
All hook up stuff in the sewer bay
Chairs,grill, lantern,dog stuff,poles,sporting goods,tarps etc is about all you can realistically get in the big bay
Heck,my fire pit and 20lb gas bottle have to ride under the dinette
I just can't see how I could possibly overload any one bay
They just aren't that big or deep
I never saw a Hearse towing a Trailer
