Congrats on the new motorhome Edward! SnapPad doesn't have the 2026 Allego Red 38 KA in their system so I don't know what size your jack feet are. However, we have a few options that will work with the HWH leveling systems. What you'll…

Hello Marc, thanks for reaching out. The Intelli-Power converter/ charger Model PD9260C can only charge lead acid batteries, it will not work with lithium. That said, we do have a suitable replacement for this that is lithium compatible. For that I…

Hello Lee, thanks for reaching out. If air won't go in at all it could be a bad/clogged valve. You could also have a major leak somewhere. Have you tried a soap test to see if there are any leaks?

Welcome back Chris. The original MaxxFan 5100k fans couldn't handle the extra voltage from Lithium batteries and the boards would burn out. A green light would come on and beep after the fan runs for only a few seconds, which sounds like exactly…
