Hi Lad,
You have probably already had your base plate installed, but just in case you haven't, I have a great contact for you: RV Specialists in Santa Rosa, CA, (707) 527-6778. The owner is Curtis, who does impeccable work. He has installed the baseplate and wiring on my new Jeep Cherokee Trailhawk, as well as numerous upgrades to my coach including inverter, power awning, and automatic satellite installations. I first found him because he is referred by Tiffen Motorhomes as an authorized service center. If you go there for any work, tell him I sent you.
Cheers,
Tim Andrews
