Modern problems require modern solutions! I do not sell or get paid for selling these and don't even know where to get them. If you have a post 2011 diesel motorhome, you likely have a DEF system for emissions control. While as a lifelong air breather myself, I adore cleaner air the system helps create, the DEF system is also very prone to failure. Often it's for simple reasons and built into the failure is the requirement to be fixed before the engine is de-rated or shuts off the engine from starting. While this can be annoying on a daily driver truck which doesn't venture far from home or repair, it can cause havoc and stress and misery if 2000 miles from home traveling in a RV. So I do recommend having one of these for emergency use to save your trip and find reasonable repair.
NOTE: I do like clean air and am not looking for conversations about over reach or egr/DEF DELETES, I do not respect or recommend either.
