Airtronic D4L
I replaced a Chinese knockoff that died in one season. I could not find parts to repair it, so I splurged and bought this one for our 34" RV. It heats way better than the 8kw knockoff we had. It is also quieter. All of the componants are much better quality. I wish I had not cheaped out the first time

perfect
Small but powerful enough to heat our long wheel base Sprinter and I think this is more than enough. I guess that smaller heater would be enough but I was worried because there is no insulation and we sometimes have to keep our guard dogs inside during the cold nights so this burner makes sure the my four legged partners are comfortable when on duty.
