Sorry, two part post because I ran out of picture upload space lol
Other mods to conserve water/energy or for more self sufficiency are..
Quick connect for a Buddy Heater inside the camper I can warm it up a little on a cool evening or morning without running the terribly inefficient furnace. I tapped into the stove manifold and installed an access point below the oven.
Quick connect for the Camp Chef stove lets me cook outside and prepare large meals without heating up the camper with the kitchen stove and sacrificing room
Oxygenics shower head conserves water and much more pressure
Berkey water filter allows me to have safe clean water regardless of where I end up. We use 5 gallon Culligan jugs with a hand pump but the Berkey is a backup plan.
2-6 1/2 gallon Blitz water cans to transport water or store extra water
60 gallon Aqua Tank II and 12v transfer pump to transfer water to the camper without having to break camp if needed. Makes a big difference if your a long way from a water source.
Viair 12v compressor and a tire repair kit/tools kind of self explanatory!
Wetbolt kit for the suspension another reliability mod
There may be more smaller mods I’m forgetting or don’t pertain to this post. My main goal is to be self reliant as possible and have a rolling “escape pod” if I need it. We keep a change of clothes, one of my Medic jump bags, a small mix of MRE and Mountain House foods onboard, and the camper is fully stocked (dishes, normal camping supplies, etc) at all times. I like to be perishable foods and comfort items away from hitching and going. The next mod I’m working on is getting one of my mobile Ham radios permanently mounted in the camper.
