I second stephs suggestion to grab a glass of vino or beer! Can never go wrong with that advice (unless its before noon and even then its ok if your snowed in like we are
).
The hybrid section here is chock full of people with 233S's and 23SS's and so on. The floorplans and interior choices change somewhat from year to year but all these Roo/Shamrock models are fairly similar as to systems so you'll have lots of reading to do.
Most trailers are the same with regards to certain other things like towing so you can spend a lot of time in the non-hybrid areas, too.
Here's what I would focus on first with your search for information. The first two items are critical to you when picking it up.
PDI and walk though - there are various lists. Print one out or let me know and I'll post mine.
Weight Distribution Hitch
Canvas - make sure to "season" the tent ends by getting them wet before you go out on your first long trip.
We have three girls and a big dog and the 233s is a great floorplan.
