I have replaced the OE converter with a Progressive Dynamics 9245 so I have a modern charger. Been looking at Roadtrek and options. A simple battery switch would be my preferred route but I do not see a convenient place to mount the switch. I have a switch and some heavy wire so that would be the lest expensive route. I do like the KISS way of doing things. Keep it simple spiritually.
A continuous duty solenoid with a switch routed near the driver will be a bit more costly and time consuming and is the preferred route at the moment. Still open to ideas and suggestions. Likely be a couple weeks before I get to this.
