My wife and I drove 2100 miles within NM about 10 years ago. Loved it and we want to do similar with our kids (4/6 yrs old). We are planning a 2-week trip in Feb 2014 and we are thinking of dedicating 6-7 days of it "on the go" hitting sites of interest, etc. We are exploring renting a small RV to give ourselves some additional independence (eating, bathroom, etc.) but don't plan on sleeping in it (except for remote sites). The other 2-3 days of the trip we might be interested in a cool dude ranch or something similar that kids would love.
We appreciate your input. Thanks!
