I've taken the 280SEL 4.5 to Cabo San Lucas and back twice, had the alternator go bad, fixed by the local coca-cola truck maintainer (Brushes $18) and popped a power window fuse in Loreto, Had the wheels aligned there tires balanced, lubed etc. Dirt roads, potholes, all that.
Up here you should have no problem, check everything as noted above. Smoother roads, available support, remember the Mercedes 1-800 help line.
Do Adjust the valves before this trip and check cam chain wear, install a new oiler kit. W7 or W6 plugs. This will affect mileage and performance. Lube the chassis, change radiator fluid. Tires, brakes, re-pack front wheel bearings.
These motors love to be run. We were at 110mph a few long times in Baja. Passing on those two lane blacktops was fun the way that motor pulls from 50 in second on up to 80+. These are the million mile cars.
This is a good time to add the "sealing" additives. They work best if run after addition, do the ATF in the gas (100-1 mix), Adjust your MAP sensor to maximize mileage (this could be a separate subj) basically you must kinda understand the EFI system and adjust MAP 1/8 turn at a time and "read" the plugs color. I've done this on long trips and dialed the 4.5 into 17-18 a gallon.
Go for it,
