The voltage regulator on the alternator will keep you from overcharging the batteries. I've not had any issues with a hot wire from the chassis batteries through my six pin connector to my toad battery. Just be sure to put auto reset circuit breakers in the line to keep things from shorting out.

When I was looking to do this I went to a RV electrician and he did not like the wire from the 7 pin plug but reccomended that I remove the charger from a trailers breakaway battery pack and wire it to the toads battery. It has some over charge safetys built in. The charger cost less tha $10 and wiring it in was easy. I have never had a dead battery since.

Look at this Bully TC-127 12V Trailer Adapter : Amazon.com : Automotive. Fused wire from battery with two wire plug.. Fused 12 volt plug from this adaptor to battery plug cable at tow vehicle... Simple and inexpensive ...works great.

I just installed Brake Buddy's Battery charger/maintainer. I think it has a diode to keep the current from going back to the MH. Also has a inline fuse. Just found the hot wire on the MH 7 pin and used a 6 pin on the toad using the same harness that wires to the toad lights.
