An auto car on a tow dolly?

Looking at the map, the only trouble spots as far as elevation are between Bend & Burns and on our side of Sisters, which as far as I'm concerned is within the home stretch. Given we're at 600ft and Boise is up over 2000ft, the biggest climb is getting there which would be with an empty dolly.

Besides my Dakota is the V8 with the OD a518. Ram 1500 guts. I'll just drive dropped outta overdrive. I just gotta keep the speed down on the descent.
just cover the basics...... good tires and good brakes. use lower gears down longer, steep hills. Don't park where you have to back up. And, as I suggested earlier, I'd tow it backwards and forget unhooking the driveshaft/loosing tranny fluids or checking the rear end grease.
In the end, every time I travel the interstates, cars being towed daily.
