I just spent way too much paying a guy for barely doing anything to re-do the plumbing and cap off some of the gas lines for safety. Just put a new water heater in, next in need is the furnace and then a water pump... need to know where and what kind I need of each. Thanks!

I did a lot of research and asked a lot of questions on here until I found a good deal on a furnace, and got all the information I found necessary in order to pull out the old furnace and put a brand new one in its place.
It was not a simple "plug and play" job, and I was very lucky to have a retired Master Mechanic to help me through with the actual job, but it can be done if you are fairly handy with tools and willing to fabricate metal a bit in order to make a new one fit where the old one was.
As has already been stated in this thread, the new ones are a different size. The exact model numbers do not exist any more, either. I made a choice to go with a new NT-30, and after living through a cold fall, I know it was the right choice. It comes on and stays on long enough to warm up the coach, where a larger one might cycle on and off in shorter bursts.
In any event, I took a lot of photos, and a lot of good people on here helped me with questions and advice, so feel free to spend some time reading it before you spend the money on a new replacement furnace and commit yourself to the job of putting it in correctly.
The first time I start talking about it in my thread is here:

But it's not until around post 145 that I get into the actual work of taking out the old furnace and fabbing the new one in.

It's pretty well done just after this post:

So, I hope you have the patience to read it all. If you do, there won't be much you don't know about upgrading to a new furnace in your coach
