Nice write up DutchmanSport. So many newbs, and we were all one at some point, get caught up in marketing.
To the OP, when you get sorta serious and actually look on the dealer lot, have them run the slides in on any unit you're interested in. Then you can get a good feel for what the trailer will be like when on the road. We have a 5th wheel, but the same rules apply. We do have full acess to the bathroom, fridge, sink and pantry. Makes for a nice convenience when traveling. You can pull off anywhere, use the toilet, grab a bit to eat and be on the road in no time.
Now it wouldn't be much of a problem to run a slide out 6-12" if needed to gain access, but the problem with that is some trailers use Schwitek slide systems. Schwintek recommends that you run the slide out fully each time you use it. By running it our only a short distance you cause the motors to get out of sync.
