We use www.mapquest.com or www.googlemaps.com for trip routing. Point A to point B. Then you can add stops along the way. Once you have the stops you can look for rv parks. We use www.woodalls.com to select a couple, then check them out on www.rvparkreviews.com We do not make reservations unless it is in a very popular tourist area like Yellowstone, a weekend (Friday or Saturday night) or a holiday. We arrive early (before 4pm) and never have a problem finding rv spots. The trip straight through on Mapquest shows 36 hours of driving. Divide that by 5 hours per day and that's 7 or 8 days to get to CA. Couple of days in Yellowstone, then 7 or 8 days back and it's doable. To keep from feeling dead tired from driving we like to leave early in the morning and stop earlier to sightsee in the afternoon. Works for us. Keep us posted!
