I believe the 3150s still only come with a cheap exhaust fan in the bathroom... In our '11 I installed a Maxxair 7500 Deluxe w/remote in the bunk room & another in the kitchen that work in push/pull fashion to keep a nice breeze flowing w/out opening windows. We bought ours used, so with part of the money saved I replaced the stock China bombs with Maxxis, added the 2 fans, and a Dynasty Mattress Deluxe.
Ours came with the "free" upgrade package from that year that included alum. rims, power stabs, power tongue jack, and 8 cu ft. fridge...
I agree that the Lacrosse is a nicer unit, but it's 1,000 lbs. more... We tow with an entry-level 3/4 ton, so with family of 5, dog, bikes, firewood, chairs, etc. we are near our max GCVW... However, the Lacrosse has extra pantry space, higher ceilings, better cabinets, porcelain toilet, and most importantly, 60 gal. grey vs. only 30 in the Tracer... Nice to have but not worth leaving behind the stuff we want to bring...
In our case, our (used) Tracer is actually an "upgrade" from the new TT's we could afford. For the same price as an entry-level single-slide bunkhouse we have a very nice setup. We're new to camping, so we really don't miss what we never had...
