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

Check out our friends TNT RVing talking about their off-grid power package! 🎥 They filmed this one at Pearl Street Brewery in La Crosse, WI — fun fact, Scott went to college there and may or may not have enjoyed a few brews at that very spot. 🍻
Always great seeing our systems out in the wild — cheers to off-grid adventures and good beer! … See MoreSee Less
