ACZL has a great idea about the spreadsheet. That's exactly what I did when I was shopping. I made a list of my preferences and targeted those things when shopping. It was fairly easy as we only wanted a rear living floorplan, so that's all I concentrated on and ignored everything else. Personally, my preferences were +/- 30', had to be a "lite" FW (I couldn't afford to replace my truck, too), opposing rear slides, 50a even if it only had 1 A/C, fairly large tanks with black being the most important. One thing I =didn't= take into account enough, was having a pantry. When DW and I went to look at a Jayco that was my #2 choice, first thing out of her mouth was "where's the pantry?" Ooops! :B Make sure you fully involve DW/partner in this, or you won't be happy.
In the end, I never was able to find anyone who had my #1 choice, a KZ, though I ended up with another KZ that I never really considered, after DW saw it and said "I really like this one". :B That, and the "I need this gone now" price the dealer's owner gave us.
