i have a 2002 gmc serria 2500hd and just got 35 FT COUGAR FIFTH WHEEL AND NOTICED ON SOME HUGE HILLS THE TEMP GOT TO 221 IS THIS OK IT CAME RIGHT BACK DOWN AFTER HILL??
I have a 2006 2500HD and see temps like that when going up a hill. I don't worry about it for a short time but on long grades I slow down a little to keep it from going higher. Brian
