Got a Carefree Add-A-Room which is a great addition for those campers who need extra space. I forget the measurements, but it ran the entire length of our Zinger's 18' awning. This add-a-room has the snapless side panels. There are just 2 brackets (each side) which attach the screen room to your camper. Although I no longer see it listed on the web site, I also have the hard door option so you don't have to mess with zippers to get in and out of the screen room, you just open the door like you would at your home. The screen door alone 5 years ago cost me almost $400.00.
This is complete BUT it does not have the brackets which need to mount on the camper (I had to leave those on my old camper) these are available and don't cost much, maybe $30 or so is my guess?? This screen room is in very good condition and was never used on a seasonal camper. It would be used for 5 days then packed away.
$500 and well worth the price.
I could ship, but would prefer not to. Shipping would be actual cost fro, Southeast (Brewster) , NY.
This is door install
and this is a place that has one with a picture.
