You won't find a better place to try it out! It's not just a place to go camping, it's an opportunity to have a live situation analysis crew on hand 24/7. So if you have anything that doesn't seem to be working right, one of us can probably give you an idea of what is wrong or maybe even fix it.
Dona (clueless campers) had a water leak last year which we all fixed right on the spot. It seemed somewhat harmless outside, but it would have caused internal damage over time.
A 13 1/2 RD, that is a small one. I've never actually been in one, but I am familiar with the floorplan.
In fact, we just had another new member join with one, mortonlykeleigh.
Here's some pictures of a '79 13 1/2' RD so you can know for sure.
