a word of precaution years ago i talked to one of the engineers at Bf and he expressed the opinion that the (soft) design of hanging tanks that flexed reduced hard shock/ stress on the attachment points when stressed by road hazard impact ,ect if you look, these are not very impressive usually either they use short 1/4 or 3/8 lag bolts screwed into 1/2 ,3/4 plywood flooring or 1/2 to 3/4 braces in the sub floor in ,in the past I had one tank drop because the the wood spit releasing the lag bolt
Has the OP said the tanks are falling out?
I think we need to wait see what the OP provides us...
I too have had support screws that were screwed into the wood and cracked, but are still holding really good.. No tanks have fell down... 17 years. I run with the fresh water full all the time... almost 200,000 miles.
I have measured the distance of the tank bottom to the bottom of the camper. The distance the tanks are suspended is enough that when the foam insulation is in place it causes the tanks to sit on the foam thus supporting the fresh water tank. The Gray tank is another story.
