Kathy, we had a 13’ Scamp without a water heater, so I added one. I just had to “T” off the
furnace propane line, and fresh water line, after adding an electric water pump. The faucet was replaced with one that also had a shower head attachment. This worked great for washing dishes, or hair at the sink and for spong baths, or running the shower head out the kitchen window to a stand alone outside shower shelter. You could heat water on the stove and place the hot water in a new bug sprayer and use it outside in a shower shelter.
If you “click” on our Avatar, it will take you to our profile. From there there are two photo albums of mods (one for our
Lil Snoozy, and one for our Scamp). These willl give you an idea of how it looked and even some mods you may like to try out on your trailer. Dave & Paula
