I am personally a big fan of the Grand Design.

I believe it is owned by Winnebago now but still seems to be a great 5th, they are all relatively light for what they are.

Cant really go wrong with Keystone tho!

Me and my wife are full time campers for the past 2 years do to my work so we have been in alot of them.

I like KZ but they do run a bit heavy IMO.

Good luck w the hunt!
