Welcome kampkiwi! I bought my 2109S last June in Ohio and camped my way home up thru Michigan and west across the UP. I visited the Whitefishpoint Lighthouse and Museum. I love the UP! I am a scuba diver so I have visited Munising several times. They have a very nice, older municipal campground right on the shore of Lake Superior.
I have been happy with my 2109S overall. I think you will find that the unit you buy is the "basics" and then you add modifications as you go along to improve it. You will find that it is a work in progress...maybe always.
My wife and I are in our 60s so the walk around bed was important to us and now that we have used it, I am really glad that we got it. The refrig, heater, water heater, TV and microwave have all worked well. No leaks to date (knock on wood).
You have to realize it is an ultra light and not built like a tank. Some of the shortcuts are a little annoying. They have these cheap pieces of paneling around to seperate the lines from open areas. Where you think you are going to have more storage you will find that half of the area is divided off with one of these panels. They are stapled in so will not be standing very long especially in the basement area. But again...that is one of the things I will change.
There is still plenty of storage for the 2 of us. I haven't used all the storage space on 3 day trips yet.
I had to tighten pretty much all of the water connections to get the water pressure to work but since then it has worked fine. I added teflon tape when I tightened the connections and I think that helped.
I treat my 2109S as a hobby. There is always something you want to add or change and I enjoy doing that.
The slideout is great and gives you a lot more room inside. Again, for the most part I have been very satisfied with this unit.
Feel free to use this forum. This is where I get most of my information, and most of it is very useful...except for herk's occassional bad jokes.
