I just sold my Pulsar XP after owning it for over 3 years. It's a fun little airplane. The problem with the sliding canopy is that it's very hard to get it to seal at the front and along the sides. If someone modified an RV to do this, the sides would probably be easy to seal, but the front would still present a problem.
I'm going with the slider canopy on my RV...I will miss the excellent visibility of the Pulsar, but I've gone flying in an RV with a slider before and it wasn't bad at all.
