Thanks all for your replies. Points well taken. Now, the issue is convincing my wife. She's now saying her big concern is me doing all the driving. She can drive but is afraid of our minivan, especially with our A-frame camper (she's short and has only driven small cars). I'm tinkering with the idea to leave the camper home and rig up the minivan as a camper of sorts; I've seen it done many ways and some are outstanding. Then, maybe she will get over her fear of driving the minivan, and the trip can be pushed through.
Ol'coot, thanks for the offer. No firm plans yet, just still dreaming (for 50 years). Time to just do it!
