As a general answer, I'd say no. I have a Nash 26X that's about 8600# and I tow it with a Ford 3/4t with a 6.0 diesel that's been gone through. The truck tows it without a problem on the flats and into medium mountains.
Last summer when I was bringing it north, I got into a long stretch of steep mountains that I believe was between Penticton and Kelowna where I wasn't liking that load behind the truck at all. I broke a hose clamp off of the turbo intake but luckily the Ford dealer in Kelowna was open and had one left.
You might make do in the flat flats, but after that you're going to run into problems I believe.
