Thanks everybody. It's finally inside and they're working on it. The hard part is going to be finding another radiator/cooler. We didn't start the motorhome every two hours like we did the night before, and it happened again this morning - with the tech standing right there watching - so at least we don't have one of those issues where the problem goes away when we bring it in.

Last night was quite interesting. The wind chill was 14 below, and needless to say, we've never been in that cold of weather in the motorhome, so it was a learning experience. We started plugging up small draft holes, then realized the entire front was one big draft. The windows are just not good insulators, and air was flowing in freely under the dash. So we rigged up a little fortress to block the drivers seat and front door off. The heat ran steady and Terry was worried the heater blower motors would go out, or the heat itself would go out. If that had happened, we would have been totally screwed. Fortunately, it didn't happen and we were able to keep the temp inside in the 60's - good sleeping temps. This morning when we brought it inside and opened all the blinds, the windows were all frozen and frosted up.

We learned a lot about cold weather camping last night, but the biggest thing we learned is we never want to be in this situation again.

Oh, Phred, thanks for the suggestion. Terry and I have been discussing the power pump pressure. It's obvious this is a pressure related issue since it only happens when the oil is thick and the entire system is under higher pressure than normal. We're also wondering the pressure relief valve is faulty because why did it blow here instead of out the pressure release valve. One thing we do know is the hydraulic oil that is recommended is 46 weight, but 23 weight works, so I think we're going to use the lighter weight.

This all wouldn't be so bad if something didn't happen every single trip we try to take. It's getting a little ridiculous now and we're going to have to take quite a few trips with no problems before we really start to trust it again......anybody want to buy a beautiful American Heritage?
