Others obviously disagree but I don't believe you need new batteries and should be looking for a different solution.
I agree with you Bill. Sure the batteries are old and they probably could use replacing, but the OP clearly stated this happens when he's on shore power and/or using the generator. Not to mention his voltage readings were decent.
Would new batteries help? Maybe. They may provide a little extra capacity boost, then again the voltages were acceptable.
Our batteries are 9 years old and certainly are due for replacement, yet our slides work as good as the day they were made.
Given the age of the OPs batteries I'd probably go ahead and change them anyway. If it solved the problem, great! If it doesn't, and I don't think it will, worst case is you did some needed maintenance - and ruled out the batteries at the same time.
