Dan, they make a loading rig for pick-ups. I've seen them load Gold Wings and full dressed HD's with them. You place the bike on the rail and tie it down on the ground and the part mounted in the truck bed, pulls the front end up and then slides it all into the receiver in the truck bed. I didn't look at it closely but I'm sure it requires some drilling in the truck bed. However, when not loaded it is very low profile and could be left in and would not take up much bed space. Not sure what they are called or what the cost, but don,t imagine they are cheap. Unless you were going to use it a lot, might not be worth the investment. A hitch mounted carrier might be the best idea???
Sounds like a wonderful trip Dan. I know you and Deb will be thrilled to see your kids. A word of warning concerning your tour of wine country. You know they do offer wine samples at some wineries so if you partake, have a designated driver.....hee hee
