It looks really good. Fellow Avenger owner here, Go over yours with a fine tooth comb. Ours( 2014 27RLS Touring Edition)was a nightmare the first year. Check your window gaskets. One of ours was installed upside down with the expansion gap on the TOP of the window.It leaked when the awning was closed our dealer never found the cause,I did.
The "tile" border over the kitchen counter bubbled and slide down the wall, I peeled it off, the glue didn't stick to the wall.
The shower drain was never connected to the drain lines,3 showers ran into the underbelly before we saw water dripping.
Both door windows had to be sealed.
And took 3 months for Prime time to replace shower door that was cut 3/4 of an inch out of square. The trailer Did NOT have one of their Rain Tunnel stickers on it that they brag about in the video.
I hope you have an awesome camper and build many happy memories. Ours now suits our needs and has been great now that the gremlins are gone.
