Last spring we had the great pleasure to meet with some fine folks from Wyoming, Eddie, his wife Aileen and daughter Laura. We spent about a week or so boondocked with them including the spectacular Valley of the Gods BLM area of Southern Utah.

They have a 40-foot wheel which they live in full time. Eddie has done a bang up job of outfitting it for their off the grid power needs. I was so impressed with the solar and power systems I asked him to give me a rundown of it while I video recorded it.

It’s been widely viewed and inspired fellow RVers Lola and Rush to ask Eddie if he would help them install a solar power system on their 2014 Keystone Cougar fifth wheel. He agreed and told them to come by the family ranch in Wyoming where they spend the summer. They were invited to hang out there while he did the work.

While Eddie was working on the various installations that would make up the fifth wheels solar power system Rush was kind enough to video record things as they went. They sent me all the raw footage and I have put it together into several  videos that I’m sure will be of interest to you DIY RV solar installers or just folks that are curious and wish to learn a bit about it.

Eddie explains the12 volt wiring

Eddie is terrific at explaining the operation and inner workings of the solar and power systems plus hands out some great little tips and tricks he has learned over the years. The narration and banter are informative and funny, even the chickens get in on the act, haha.  Looks like they had a lot of fun with the project!

Eddie finds a path to run the solar wires

Like all projects, there are bound to be hiccups along the way. They had originally gone with a Nature Power 2000W inverter like Eddie has in his rig, but it actually showed up damaged from shipping. They ended up spending some extra dough and went with Magnum MS2012 Inverter/Charger instead. Looks like a real sweet unit!

I hope you find these videos helpful, I sure do. I look forward to meeting up with Lola and Rush down the road sometime and video the final results, including a real good look at the Magnum’s installation. It will be interesting to find out how they are using the system and it’s performance in real world off the grid scenarios.

If you’d like to ask Rush or Eddie any questions they both hang out over on Love Your RV Forum. I’m sure they would be happy to answer them. Eddie has also recently started up his own business – Mobile Homestead Solar Services.
