So, back to the trailer. Having satisfactorily tested my triple-tank fresh water theory and cleared a path for their installation, I had to think about securing these 21 gallon vessels. Once filled, the tanks will weigh 174 lbs. each and clearly cannot just sit atop the belly skin with little to support them. So I purchased 20+ feet of heavy-duty water heater straps and fashioned slings draped from the steel cross members.
Now I should mention here that there was a fair amount of preparation required to get the spaces under the old sub-floor ready for these tanks. For one, the top side of the belly skin was extremely dirty. Sixty years of road grime and dirt, kicked up on the dusty trail, had accumulated. Check this out:
Once this grime was removed, I found jagged screws pointing up from the belly skin where it had been stitched together. Obviously, these had to go, lest my carefully nestled water tanks get pierced, leaving me dry and parched in the wilderness. So they were repaced with nuts and bolts which I dropped down from the top of the skin. Problem solved.
