We've done a few hard pushes ourselves! Two years ago...Baton Rouge to North Wyoming (about 1700 miles) in under 40 hours towing our camper! Most recently (about 5 weeks ago), round trip (towing a hydraulic dump trailer) from northern Wyoming to Metropolis,Il.,and back with a tractor. Left home on a Tuesday at noon, back home Saturday. Five (5) days, four (4) nights in the cab of a Dodge truck....Is pretty tough on two old folks. Sometimes you have to cram a lot of living in a small time slot! ;)
But,If you ain't liv'n on the edge...your tak'n up too much room! :B
