I would highly recommend The Motorhome Workshop. I wanted to replace my old gas powered Truma boiler for a new diesel powered Truma D4E. Truma themselves said that it could not be done in my Motorhome space. However the can do attitude of the guys at The Motorhome Workshop proved that it could be done and without any alterations to the van. The new boiler works seamlessly and the phone control with the iNetX is a game changer from my old system. Massive thanks to the whole team and I will definitely be going to the Motorhome Workshop for any future upgrades.

Campervan was displaying error code on Truma 6E Control panel, meaning no heating and no hot water. Was fitted in for a consultation the day after I rang, everyone very pleasant, problem was diagnosed very speedily as fault with the control panel. They had one in stock so replaced and everything working again. So excellent service, charged for just 1 hours labour plus the parts, so very, very happy!

This was my 2nd visit to Sunstore to have a new Truma water boiler fitted to my classic Hymer S700, fantastic service as always. Thank you, it’s great to have hot water coming out the taps once more.

Where do we begin. We had researched for weeks if not months for a reliable and trust worthy company to educate us on what we needed for our motorhome. We had limited knowledge of what we need however we knew what travelling we wanted to do. From the very first call Tom was patient, informative and extremely helpful. We felt that a face to face meeting would help us to understand and decide what we needed. Once again Tom took the time to explain our options and within minutes we had our quote. We instantly knew we had confidence in Tom. Today we have collected “Burty” and he’s new solar panel, battery, Wi-Fi and gaslow system. We had the pleasure of meeting Ian who explained the information we needed to understand our new additions. Thank you and the rest of the team too for making a big decision for us so easy and simple. Burty is now perfect to pack and go. THANK YOU

The Sunstore team fitted a new 3Way fridge for us a few weeks ago. The fridge was performing very erratically. Thankfully Tom took a personal interest in our case and he managed to navigate a way through what was initially limited advice from the manufacturers helpdesk to speak with a member of the manufacturers engineering team and instigate a solution which appears to have resolved the issue. The Sunstore proactive intervention has thus avoid what was heading towards being a complicated warranty claim. We cannot thank Tom and his team enough for sorting. As the first point of contact, Edward in the Sunstore office is super helpful. Rick & Debs
