Greetings Cker! We always stop off at Lake Murray for a fresh water rinse when coming back from the ICW.
The 2120 with proper trailer travels well overland. I use a AWD Mountaineer, and it handles the Mokee D no problems. I personally don't want to trailer anything larger than this boat.
My preference tends to solid, well built, no frills, easy to modify and this is what attracted me to the 2120. I like simple - porta potty, helm station you can get under to access wiring, no thru hull fittngs to have nightmares about, etc. I learned thru Nick from Spartanburg (and experience) that everything on your boat is broken (you just don't know it yet), and the simpler the better. Nick and I stopped at the factory unannounced one day, got the tour from a very gracious BoatGirl and I came away wanting a 2120. No regrets.
I have been very fortunate to have a clever brother in law willing to make custom mods to the Mokee D if I provided the money. It has made traveling on board much more comfortable (we sleep aboard on water and land with AC or heat). That said, you need determine if the pilot house measures up to your comfort level. We found two adults OK, but three made for shorter trips. I believe the PH on the 2120 and 2320 are pretty close if not the same in size.
I love looking at boats. Have not been forunate enough to look over a Steiger or Judge, but have looked at C-Dory's Venture Cruisers and Tomcats. Didn't care for the Cruisers as no self bailing cockpit and no cabin liner to foil the sweating at the time I looked. The Tomcat might have potential for a trailer cruiser. I'd want a 1 ton diesel or V-10 TV in front of her tho.
Good luck on your search. Take your time and be sure to spend some time aboard before you buy. PM if you are interested in a cruise on Lake Murray this fall. Probably won't be the area before October tho.
