Default CAT C-7 performance

Hi,
I recently took a trip from Los Angeles to Yosemite, San Francisco, and Santa Barbara while towing a 2007 Honda Odyssey on a tow dolly.
I could barely go up some of the hills. I had to down shift to 3rd gear while going about 35 MPH. Is this normal?
I do have to say, my temperature gauge was fluctuating quite a bit. It also over heated a few times while climbing the CA-140 going to Yosemite. But again, it was one of the hottest days, so I'm assuming it's 'normal'.
I called one of the Freightliner facility here in So Cal, and they wanted me to pay a few hundred dollars to see what the problem might be, and it will go toward the cost of fixing the problem, if there is one. I was also told by a neighbor that I can 'up rate' my C-7 to 350HP from 300HP, but I might start to have over heating issues.
Any comment/suggestion is appreciated.
