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

Getting packed up for the RV Supershow in Tampa next week!
Mike is already on his way south, squeezing in a few jobs along the route… and somehow managing to fit in some college football too. Priorities.
We’ll be cheering on IU along the way—Go Hoosiers!

Every now and then it’s worth looking in the rearview mirror.
These are some of our earlier off-grid power builds, and while the installations have evolved, our approach hasn’t: listen to the customer, design for how people actually camp, and don’t cut corners.
These early projects helped shape what ABC Upfitters is today—and we’re proud of every step along the way. … See MoreSee Less

They stand by thier work.
We sure love ours! Still smells of Mikes cramping calf muscles, regret, and broken dreams, but the power package has made our camping lives so much more amazing! Thank you ABC Upfitters for all the hard work.
