Coach Battery Question

I can't get a straight answer from the repair shop (), so I hope someone can answer this. My Winnebago came with 2 deep cycle RV/marine batteries, one for the coach and one being used as an engine starting battery. The 2nd one will not take a complete charge, and seems to 'top out' at ~90% on my automotive battery charger (not converter). It is set on 12V, 2 amp deep cycle charge.

Will it hurt my other deep cycle battery to use BOTH batteries for the coach, as long as I have the wiring correct? Or will it fry my newer battery? I'd rather replace the older one than replace both.

I bought a new reserve-start automotive battery for the engine, by the way.

For a chassis battery, a Starting battery is better than a marine deep cycle. What voltage is the battery reading at 90%? You should have the batteries load tested and also do a specific gravity test on each cell. Cleaning the terminals and grounds wouldn't hurt either.
