i have an l5 type heater from corwoods, i must say it does work like they said it was, it was worth the money to keep me working however it drives me insaine !!! get leaks , hose goes tangley and hard to move round !!! im going to give it another few months trial though because it certainly cleans well and looks cool in the van.
the service i recieved from corwoods is worth mentioning because it really was excellnt, i believe the guy i spoke to was the website designer and his customer service was of the highest level, that good infact that i will use this company again
