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

🚐🔋 Another busy week at ABC Upfitters! 🔋🚐
Following up on last week’s post, we once again had two Thor vans and a Brinkley 5th wheel in the shop—plus, we added **another 5th wheel** to the mix! Off-grid power upgrades are in full swing, and we’re loving the transformation these rigs are getting with Mastervolt’s high-quality components.
Fun Fact: One of the vans is getting a full system cleanup, adding battery capacity and upgrading the alternator for a big adventure "across the pond."
Whether you're upgrading for full-time adventures or just want the freedom to go further, we’ve got the power solutions to keep you moving!

🏀 It’s no secret—the folks at ABC Upfitters are nuts for college basketball! 🏀
With our own court in the back of the shop, we like to think we know a thing or two about the game (even if our jump shots say otherwise 😆). You better believe we’ll have an eye on the games all weekend—because March Madness waits for no one!
