house or chassis batteries used for slideouts

We also have slides that will not operate with the engine running. Nor will they go out until the jacks are down. So it isn't all or even most who need engines running. Sure sounds like bad design to have any thing to do with the house on chassis batteries. Sounds like manufacturers who skimped on designing number of house batteries to handle the load of all of the house functions.

Very FEW Motorhomes have the design that the jacks are to be extended before the slides operate. Me thinks you have an HWH system for both Jacks and slides as HWH DID offer that type design. But it was NOT standard for HWH jacks systems and only if you had Hydraulic slide system. The design of "which" battery system has nothing to do with shortcuts or cheapness by the OEM. It is just what the OEM and their Engineers decided to do. Some require the Engine running to make sure you have as MUCH battery power (Alternator) to power the system---usually Electric slide rooms. Some require the Engine OFF as a protection from the slide being able to extend in transit. There is NO set rule and their is no system that is "better" than others. My preference would be for the slides to operate anytime the engine is running. Which would mean BOTH battery banks would be online, so if one set was low the other and the engine Alternator would supply full power. Doug
