Gasser..came on either Ford or Workhorse chassis...if workhorse chassis make sure brake recall has been done...widely available info about that..even a workhorse site where you input the VIN and it tells you whether done or not...Tiffin Allegro ...decent unit plus Tiffin stands behind it if you are willing to go to Red Bay...there were a few issues with basement floor and roof...Newmar, really can't go wrong there..they build a nice unit....and Fleetwood Discovery is a decent diesel pusher but some of them had electric leveling jacks that drove people crazy...the boot of the jacks would get water in it and thus make the jacks go bonkers...I have a friend who traded his Discovery in just because of that...find the floorplan you want and go from there...that's the most important for your own sake, otherwise your better half will always get on your case...:E
