Got a Dometic screen room from Ebay for the Ventura
. We had to change the location of the 2 outer poles fit the trailer and put on pads so the rivets didn't scratch. It will also need a bit of altering to fit the sides better. We used for the first time this week with a trip to Kimble Lake in Meadow Lake Provincial Park in Northern Saskatchewan. It comes with a piece of screening for under the trailer to block off the little ankle biters that was a godsend. All in all a great buy.
Installation was very straight forward slids into the awning
rail. We used bunge cords and tarp clamps to attach the walls to the trailer until we decide if we want to rivet the snaps on the trailer. The Ventura
is pretty tall but the top is only 8' so the top hangs over and we may have to take a dart out of the sides to fit better.
BTW Meadow Lake Park is a great place other than the dirt roads!
