Brakes on my Coachmen 18K seem to be hot, to hot,and sometimes make noise, temp on right side 250deg, and almost 300 on left. no burning smell. Going in to Ford to check out, But they will not give me any info. on warranty, unit is under the three yrs, and has 20,000 miles. Called Ford they connected me to three different people but no info what was covered, same with ford service dealer. I got the
temp. readings right of the roters with heat gun.

Depends and especially with how hot the fluid gets. Brake fluid will boil at 212F if it's old enough. Whatever the case, you need it checked out, but normally if there's no real difference between them, then most likely they're operating normal or they're being abused in some way.
You didn't give much info, as to traffic on level or at the bottom of a 5 mile 6% grade.
