At Christmas 2021, I asked for and received a propane extend-a-stay for our Freedom Elite 30FE.
The extend-a-stay allows for attaching an external propane tank to the system. This comes in handy during an extended stay at a campsite when the main tank runs low, thus preventing one to have to break camp to go and fill propane. You just connect an external tank and you are back in business.
However, when I went to install the device, which I thought would be a plug and chug task, I discovered that it was going to be a much more complicated operation than I was willing to start at that time.
I’ll briefly describe where the propane tank is located on our RV.
The tank is mounted just forward of the rear wheels on the driver’s side. The hose coming off the rear of the regulator curves inboard so it clears the rear tires by less than a foot.
By adding the extender in between the tank and the regulator would have left no room to mount a hose on the end.
Thor had originally mounted a mud flap forward of the rear tires presumably to protect the propane tank and its components from any road debris the tires might throw up.
While the top edge of the mud flap was securely fastened, the bottom of the flap was attached with a cheap sheet metal bracket using one fastener mounted to the sidewall of the RV and one fastener to the flap.
I discovered early on that the fastener attached to the side wall tended to work itself loose and would tighten it. However, after a long trip, I discovered that that fastener had fallen out, causing the mud flap to rub on the tires which resulted in this.
That’s why there is no flap shown in the previous photos.
I spent a lot of time thinking of the best way to install the extender, reroute the propane hose and still be able to reinstall a new mud flap.
The existing installation consists of a hose attached to a manifold under the RV. This manifold distributes propane to all of the appliances. The other end of the hose is attached to the regulator. All use 3/8” NPT pipe threads.
My plan was to use a 90 degree elbow at the regulator to route the hose up and over the tank. However, I couldn’t figure out how I could do this with using a fitting with pipe threads on both ends.
My solution was to install a brass 90 degree elbow with 3/8” NPT male on one leg attached to the regulator and 3/8” SAE male flare on the other leg . I then installed a 3/8” female NPT coupling on the loose end of the existing hose and then a 3/8” male NPT/ 3/8” SAE female swivel adapter into the coupling. The swivel allowed me to connect everything in the middle of the run.
I carefully used the proper (yellow) Teflon tape on all of the NPT threads.
Regarding the mud flap, I found a similar size/shape flap on Amazon and used the original damaged flap as a pattern to locate the top mounting fastener holes.
I then fabricated a mount for the lower flap using a piece of 1/16” steel flat that was laying around in my workshop. I attached the top end of the new bracket to a piece of frame under the RV and attached the lower end of the bracket to the flap using a machine screw, fender washer, washer, lock washer and nut.
This is what the flap looks like installed.
I’m sure my bracket will hold up much better than the one originally installed by Thor.
