You don't specify but most Deltran Battery Tenders are only .75 to 1.25 amp output. If you have any load at all on the battery such as a radio, it will almost continually be charging.
absolutely how they work.One has to realize there not a battery charger per say.If your batterys get run down u will need to charge them fully before any tender will keep then up and as already posted
any amount of draw on them while sitting a battery tender will not keep up.If for some reason U need to have a constant draw from your coach batterys then link them to your house batterys and the house inverter/charger will keep them up(one idea)
To answer the OP question based on what you have posted i would say your house batterys are fine
