I would try to put an Equalizing charge on them before giving up...but a pair of T105's WILL provide 225AH's at 12Volts. This means you have 115 ah's or so to work with before you need to recharge. (12.2V at rest.)
"All lights and stereo running" is hard to make a judgement about...but let us assume 3 amps for the stereo and 7 amps for a few lights and you have 20 amp hours used in 2 hours...not nearly enough to pull your battery down to 12.3 if it was in good shape.
But...it does seem like a pair of T-105's is sufficient for your weekending if refrigeration or other big amp users are not on board. I'd keep it simple and replace with the same if you can't revive the old ones.
