If you haven't cleaned(washed) your radiator within the last 6 months, I would really recommend that you do that before your trip.

I clean ours every 6 months and recently went east in 100+ temps and the temp guage never got past 205 degrees and that was going up through the Bighorn mountains at over 10,000'.

These engines kick up a lot of dust when going down the road and I think frequent cleaning is a must for keeping the engine running at safe temps JMO.
