We make your motorhome self-sufficient.
Home is where you park it. Solar systems, lithium batteries, climate technology and more – planned, installed and handed over with German craftsmanship.
Motorhome upgrades – from experts who camp themselves
Upgrading a motorhome takes more than parts: it takes a partner who listens, gives honest advice and installs with precision. That is what GNS Reisemobiltechnik has stood for over roughly 30 years in Mönchengladbach – and, since 2021, in Bruckberg near Landshut. A family-run business led by Julian Paval, we combine meticulous German workmanship with a genuine passion for camping.
Our speciality is off-grid capability. From a single charging booster to a complete self-sufficiency package, every solution is engineered for your specific vehicle – brand-independent, using components from Victron, Truma, LIONTRON, Votronic and Dometic.
