Owner report 11484164 · 2022-09-13 (September 13, 2022)
This Thor Scope Class B RV is manufactured with two auxiliary batteries outside of and under the chassis to power electrical components in the RV. These batteries are not associated with the Promaster chassis/engine power and appear to be installed by the RV manufacturer.

That cable was connected two one battery but was left loose and di…

Owner report 11580034 · 2024-03-29 (March 29, 2024)

Owner report 11703377 · 2025-12-05 (December 5, 2025)
This is a Thor Scope RV built on the Promaster 1500 platform. The incident involves the Onan gasoline powered generator, which is directly connected to the fuel tank. Next to the generator in the fuel line, there is a small white inline fuel filter connected by the fuel hose going over a nipple on the filter and reinforced by a hose clamp. In my case, the hose clamp was not installed sufficiently over the nipple (far enough back on the fuel hose that it did not completely engage the nipple), and presumably from vibration associated with the gen…
