Here are a few mods. Ii was a pain to get a wrench in and around the axel and wheel to open the plastic plug on my water tank so I I installed a garden faucet in place of the plastic plug. I empty the water tank every time I use it to keep it fresh and reduce weight when traveling.
I also put garden faucets on the hot and cold drains lines..it makes it really simple now to drain the lines when I am winterizing.
This is a real simple mod that is easy to do and makes things easy when draining the lines.
