Question:
I am considering the demco air Force 1 braking system to connect to a factory installed Spartan safe Haul system on a class A diesel pusher with air brakes.that I am considering buying. Will I need the battery charge line RM156-25 with the air brake system as I dont know how much draw there will be on the battery? the toad will be a 2021 Jeep Wrangler. I am building the parts list required so far I have Base Plate BX1139, tow bar BX7420, Braking system SM99209 and wiring BX88308. Will I need anything else?

It looks like you've got a good handle on what you need.
The # SM99209 second vehicle Air Force One kit is what you'd need, because the Spartan Safe Haul provides everything necessary on the motorhome end of things but you'll also need the # SM6296 jumper kit to connect the air system on the coach to the Air Force One system on the Jeep.
The Blue Ox # BX1139 works great on vehicles with the stock bumper with the plastic bumper cover and the
# BX7420 Avail tow bar would be a good choice as well. The only problem I see is that the bulb and socket kit included with the # BX88308 isn't compatible with your taillight assemblies, there's not enough room in there to accommodate the bulbs. Instead, I'd recommend the # RM-152-98146-7 Roadmaster Diode kit.
I would indeed recommend the # RM-156-25 charge line kit to help keep the Jeep battery topped off while you're towing but it will still be a good practice to fire up the Jeep for a few minutes whenever you stop. You can use one of the unused circuits provided by the umbilical included with the # RM-152-98146-7 diode kit to connect to the coach. You'll also need the # RM-751490 stoplight switch.
Finally, if the installed base plates have a greater than 3 inch difference than the receiver height on the coach, you'll need a high/low adapter. I'll link to our selection of adapters plus to an article that shows how to determine which adapter you'll need.
