Or how to mount 2 – 100 lb propane tanks onto a tiny house
To mount 2 – 100 lb tanks onto a tiny house, one should not just bolt a bracket onto the last steel member as the downward weight will twist the steel and premature failure. What we did was weld together steel that had one long cross member that would help carry the weight 2′ in from the end of the trailer, and be welded to the trailer beams as well as welded to the end beam on the trailer.
Then we welded plate steel to the boxed area, with corners cut out so that water would not collect where the 2 tanks would set.

The upper cross member is bolted to the house wood frame with arms that project into the tank shroud which allows for a padlock to be inserted to secure the tanks to the wall, as well as easy removal for filling the tanks. This also acts as ballast to the trailer and will reduce the tongue weight by 100 lbs or so.
