We are close to pulling the trigger on the 321RSTS as well. I am considering ONLY Jayco based on my experience with Starcraft (Very good) and the fact that Jayco was the first in the industry to offer a 2 yr warranty.
Not to significantly hijack the thread, I would like to ask a few questions on the 321;
1- if you have a TV that is 2013 or later did you have to mod the truck or trailer to mate level and have 6" of recommended bed rail clearance?
2-if you have 12 or 23CF fridge do you load it up while traveling (ie, slide in)? I am wondering if it can take the weight.
3-can you sleep on the bed while the slide is pulled in?
4-how are you managing with the limited cargo carrying capacity. the one i am looking at has levelers, res fridge and has CCC of 1350#
