Decided to pull my 2500lb tent trailer up to Donner Lake for a week of camping. Unfortunately, I ended up travelling on one of the hottest days of the year(Sat July 22). I was travelling from the East Bay, up I80 through Sacremento and up to Donner Lake. When I hit Rocklin the outside air temp gauge read 113F. <img src="/forums/images/graemlins/scared.gif" alt="" /> When I got to Donner the temp was still 92F.

In the end the Truck pulled like a champ. The coolant temperature gauge never budged. Not even a little bit. Oil pressure stayed nice and high (55-60psi). I really worked the engine to keep the truck up to speed. Was doing some 5000rpm pulls at 60mph. Saw quite a few vehicles pulled over (broken down).

I have owned the truck since nearly new, and have performed normal maint. (although I am not a maint freak). I drain and top up the coolant every other year. With the way that this truck (and my '90) have behaved (coolant temp wise) I dont understand the references to overheating and Auto Trans temperature problems. I use Mobil 1 (Dex III) in the tranny. Maybe that helps.

Just wanted to share. <img src="/forums/images/graemlins/cheers.gif" alt="" />
