I got my base plates from camp world and then they installed them for $39! I think they are at around $60 now. Their price was about $100 or so more than off the net but the install prices made up for it. Most shops unless doing yourself are around $100/hr cheapest we had was $75/hr at a small rv shop. CW also installed the light kit, if you go this way make sure they include a charge wire if ya need one for the brake system.
