I used the chassis batteries because they are in the back next to my engine. If both house and chassis batteries are charged while driving, either would do.

Do you use a 1 wire or 2 wire connection? Do you use Pos. to Pos. connection?

Ground wire is in 6 wire umbilical between toad and RV for all lights and battery. Yes, positive to positive, with auto reset circuit breakers near both batteries to protect against shorts and drawing too much amperage as starter will cause a temporary imbalance.

I did a stright wire from house battery (pos.) to SUV battery (Pos.) and I drove about 70 miles and battery was dead. I used the reset cbs. Dont know why it didnt work. Maybe I should do 2 wire if not going theu 6 wire plug? Also the book says nothing about what position to put the key.

Yes, you need a ground wire to complete a circuit between the batteries.

I two a 2012 Ford Explorer.

1- I use a "Toad Charge" connector. Works just fine.

2- I've found that the Ford system works best if the key is turned to a mid-point position between Off and Accessory. You need to play a little with the switch but there is a point of hesitation mid way between the first and second positions. There are four positions, 1- Off, 2- Accessory, 3- Run, 4- Start. The sweet spot is between 1 and 2. Another Ford owner taught me this.

Since you need aux brakes on the towed vehicle (Supplemental brakign system) the easiest way to do it is to put in a US-Gear Unified brake decelerator to stop the truck...

This system INCLUDES a charge line for the towed.

True story: Left Detroit on jan-2 2006.. No tail lights on towed, the motor home was not (A diagnostic tool found) providing power to that circuit... Double checked the US-Gear schematic

Turned on the parking lights and made the 2,000 mile trip before getting it fixed.

No problems, 2,000 miles, several days and no problems.
