We are also backpackers and have camped for multiple days/nights out of a backpack and slept in a two man tent. So you can imagine how a smaller trailer, like the 22G, would feel in terms of space when making such comparisons. I can see where the 22G may seem a little cramped if you are use to a lot of space. And for the price, it doesn't cost much more for a larger unit with slides. I'm not going to lie, our Jayco was a little cramped for us.
We just sold our Jayco yesterday to our Arctic Fox dealer. It looks like we are going to place an order in May for a 2016 model.
