Can understand your desire not to just spend $6k on a rental, but when you consider what you could lose on a purchase, it may not seem bad.
You didnt mention any experience with this as a travel method, nor have you mentioned past experience driving something of this size. You may find the travel part to be more nerve wracking than going to work, for both you and your family. A rental for a weekend trip or two would be my first suggestion to get an idea of whether this is a method you and your family can enjoy together.
Figure 300-400 miles a day for your travel time, confined in the size space youre considering, will your family be happy together? Do you have enough time available to throw in a couple of days off to let everyone unwind, maybe near a theme park or other venue.
It would have been great if you could have started this process a month ago to try that.
Happy motorin.
