That's really cool. I can tell you that the picture you have there is much better than the OEM cargo camera!
I'm impressed with the amount of modifications and tinkering you've done with that truck already. Now you need to hook it up and give it a good workout!
Unfortunately our camping season is over; I winterized and covered the trailer last weekend. We could have gotten another trip or two in but it was good to get it wrapped up while it was nice and dry. We also had to put our beloved yellow lab down 3 weeks ago which really took the wind out of our sails. But we'll be back at it in the Spring!
