Query: Works great, but HUGE

High quality product and works well. Exhaust smell is much less. I got it for $109 and wouldn't pay any more than that. It is very large. Probably looks a bit like over-kill on our 19 ft Roadtrek. We will only take it with us when expecting to dry camp a lot as it takes up a lot of room. Designed more for big A RVs I think. I painted it white to blend in a bit better with our rig.Solar is looking better and better to me (smile)
