G'morning from Casa Grande, AZ. Don't know what happened to Arizona, but, MAN...it's bouncing below freezing at night. No snow here yet, but areas up around 3,000 ft are seemingly ALL gettin snow...from heavy to a dusting.
We had a Hydro/Aqua Hot unit in our former RV, a 40 ft. (06 model) pusher, but now have an Oasis in our current (08 model) rig. We're real full timers so do get opportunities to need the furnace from time to time....like currently here in Casa Grande.
Anyway, we really like our Oasis unit and have found it to be significantly quieter than our previous Hydro-Hot, and it burns cleaner also. We'd certainly recommend the Oasis.
