Used our 2002 Alpine MH over season with no problem. After washing items near battery case found engine batteries dead. (had just purchased last year).
Did use boost to get engine started, after I dried battery compartment out completely, but now cannot seem to charge engine batteries. Also motorized entry step not functioning. Ideas???

Do you have a multimeter to measure the voltage at the battery terminals? If you have 12.x volts there it is not a battery problem, look for a bad connection along the way. Steps are generally on the chassis battery so failure of that circuit would disable the steps. I am not a tech just a long time owner and have found just about every failure to be simple to fix, sometimes hard to diagnose.

Check battery connections for tightness. Also check battery output with a meter. Limited amounts of water is normally not a problem for batteries.

A volt meter is an RVers best friend. It does sound like you may have shorted the batteries. If driving is not charging the chassis batt, you have problems. It's unknown if your chassis batt is charged on shore power. Driving or running the engine for 30 mins should put the chassis batt in good shape. If not it's probably shot. You can take it to a battery center and have it load tested.
