What Do You Camp In?

WHAT OUR CUSTOMERS ARE SAYING
We would highly recommend ABC Upfitters. We own a Thor Tranquility 19L and wanted to add more battery (from 400ah to 800ah) and made a trip to Elkhart while we were visiting family in Michigan. Their team accommodated our tight time frame very well and the cost was in line with our expectations. Communication throughout was responsive and professional. Pre and post work walk throughs explained some of the problems we were having and how they would be resolved, as well as the inner workings of our electrical system. Now we have ample battery for our off-grid mountain bike trips.

I rarely get impressed with customer service nowadays, but you guys are the bar that others should measure themselves against. I appreciate you and hopefully, one day, I can return the kindness you have shown.
– Roy M.
A big thank you to ABC Upfitters. We traded in our 400ah battery and they installed two 460ah batteries. This will be very beneficial during the summer in Texas. We turned the AC on high, with lights and the fridge running, and we had over 10hrs of battery life!! They even cleaned up some lose connections and made a few other repairs for us as well. They are a great, “down to earth” team and very easy to work with. I highly recommend them if you’re looking to do a battery upgrade

🚨 *Warning: This video may cause drowsiness!* 🚨
Look, we get it—watching paint dry *might* be more thrilling than a video about charging a Mastervolt battery with a small generator. But if you own an off-grid power system, this is *need-to-know* stuff.
So grab a cup of coffee (or three), settle in, and let us walk you through the process. We promise it’s more exciting than a dead battery in the middle of nowhere.
🔌⚡ Watch now and stay powered up! (Even if you fall asleep halfway through… we won’t judge.)

We bought the Honda 2200 generator based on your recommendation. Here are a few things we really like about it. Our solar package typically charges our batteries just fine. In the event of multiple cloudy days, they can use a little help charging the batteries. This generator does a great job doing that. It is light enough to move in and out of our truck bed with ease. It doesn’t take much room in the bed of the truck. You can use a regular extension cord between the generator and rig. The 50A cord can stay in the pass through.
🔋🚐 Custom Off-Grid Power System with Stressless Camping! 🚐🔋
We had the opportunity to build a custom off-grid power system for our friends at Stressless Camping—and afterwards they filmed a system overview video. 🎥✨
If you’ve ever wondered what it takes to power an RV off the grid, check out the video. From high-capacity batteries to seamless solar integration, we designed a system that lets them camp stress-free, anywhere the road takes them. 🌞🏕️
👉 Watch the video now and see the system in action! youtu.be/lgWSXtkTtOw?si=q4TReHewhRaAx_Kg
