If you want to see the west fly into vegas then go to saint George Utah then north to Moab on the way see Bryce and Zion then Moab, south to 4 corners then down to Grand canyon then west to cali and north to mammoth, lake tahoe, Bodie then west through truckee and then to the coast and up north through the redwoods and up to wild horses. Throw away your kids luggage since they will grow out of it anyway and pack a pair of corner guards for your Bronco and fly home. Know nothing above frisco so other will have to advise. Skip frisco it just a pain in the arse.
Or at least bring an empty suitcase (largest size) so you can pack it with parts and send it home...
