I have been mostly a lurker on the forum, except for a few responses to baglo posts. I finally visited the Escape factory yesterday to look at the 19, but also had a peek in the 21.
Stepping inside, the first thing I noticed was the bed area was nice and bright from the large window. It was facing south on a sunny day. Good for daytime, and I think I recall you saying you like to stargaze at night.
Comparing it to the 19, the main galley area has more open floor space, and the kitchen counter area is so much larger. Look at the space between the sink and cooktop in the photos.
I liked the shelf behind the passenger side bench in the dining area.
I didn't really check out the closet and bathroom space.
I thought the bed area in the 19 seemed more open than the 21, although I did not actually lie down on the bed in either of the trailers to compare. A bit narrower than the 19's queen size.
I am thinking that Reace can add a Quahog 2 graphic at the factory. After a few mods of your own, you can rename it as Quahog 2.1
I am guessing that you have had Quahog longer than any of your other trailers. (6 in 4 years?) Not surprised you are upgrading after a year, but that you are planning to switch to another Escape says something.
