Outdoors RV Creekside in Eastern US? Creekside vs Nash

I'm still shopping for another rv and I'll be looking at a tamarack trail 721fbs tomorrow(2/1/14)It is also an outdoor rv product, and an ultra lite.It is a 2010 model that has been discontinued. I'd be interested in any info on the tamarack line, good or bad.It is a pretty big step down from my last terry 280fqs, but half the weight and a good price.I'm just concerned about going with an ultra lite.
