Any help would be appreciated!

I'm only half way familiar with it - just a little background: The early version Revcons used a Toro half frame bolted to a ladder frame for the rest of the coach. When the big Toro went obsolete, Revcon designed their own drivetrain, which is what I have. But there are many similarities in the design, which is why I have some familiarity with it. That and being on a forum with those who talk tech about it, you learn a bit. The assumption is that once the engine is out, you will probably want to lower the ride height, so the suspension will at least halfway work. Easy to do. I have a photo somewhere of adjusting mine, which is very similar, so it will make sense. I just can't find it yet. I'll post it later.

I figured your towbar was custom, but assumed Readybrake receiver was worth a look. Not much good when you don't have anything to attach a cable to.
