We decided on using one big fixed mounted tank vs two removable 20lbs tanks. The debate was whether or not we would find places to fill up the fixed tank on the road; as where with two 20lbs tanks, you can exchange them out just about anywhere.
The Flame King YSN293 is a 29.3gal ASME approved horizontal tank. We ended up finding plenty of places to fill our tank including Menards, Loves, U-Haul, and of course, any propane supplier. With this large tank, we don’t have to fill but every couple months at most. The winter is a bit different due to the propane consumption from the use our furnace. During those colder months, we fill it maybe once a month.
Raising the propane tank into place.
The brackets on the tank did not line up with the corrugated decking under the bus, so a steal plate was used for a substructure. Some 16 gauge steel was cut to length and bolt holes were predrilled with a step bit. The length was cut so there was no overhang from the tank bracket to the end of the steel without support. As you can see in the picture above, it extends to the rib past the bracket.
This was done to insure there was no movement while traveling down the road. Grade 8 bolts were used to attach the tank to the flat stock steel, then galvanized self tapping screws were used to attach the flat stock to the bus. The steel could of been welded to the bus instead of the screws, but we didn’t not have a welder on site.
A salvaged RV panel was used for our access door. We spot primed any bare metal after making cuts into the structure of the bus. This will reduce any rust issues down the road.
