Here's a picture of our Aristocrat travel trailer. From what I can tell it's a Mainliner model. Love the heck out of it. I forgot I had this picture from when we camped at Two Medicine in Glacier.
You can see the improvised sliding door handle thing we made for the screen door. It should be made out of metal and it slides back and forth and allows you to close the outside door, and then when the main door is open you slide it over to keep out bugs. The problem is you forget it is slid over to keep bugs out and you close the main door. Then the door handle bends the little slider thing. So we made one out of some cardboard and covered it with duct tape. It works slick. Since we made it, we both forgot it was slid closed and then shut the main door. With the cardboard version it just pops out and no problem. If you did that with a metal slider it would bend and be a problem.
It seems that now everyone is towing great big huge trailers. I can't imagine doing that unless you were going to spend a lot of time out on the road. This little Aristocrat has everything we need. Honestly, sometimes bigger isn't better.
