Joe a couple if thing. First please add what rig you have to your profile. When I'm on my phone it doesn't show up.
If you have low WP at the site you are try running the water pump. It should give you the WP you need to run the WH. Look for a shower head that mixes air in it. There are a couple out there and they help a lot. Read the old posts on the forum about the Gerrard WH. There is tons of info posted and more than I can relate in this post. Are you using water from your tank or the campground? I know that in AZ some places use a cistern and that could be the problem. If the water is warm coming in it is almost impossible to get the temp right as there is not a thermostat in the water line. If that's the issue call Garrard and they can send you a BTU limiter that closes off half of the burners. We used them before the temperature dial they use now.
