Are trucks not for the middle class anymore?

My wife and I do well financially, but I simply can't bring myself to get a loan on a vehicle. My 2006 toyota tundra threw a rod last year at the peak of pricing. I bought a 2013 Yukon with cash and start saving for a truck but the prices seem out of reach for most. I wouldn't mind getting an older pre emissions diesel truck but with the insurance rates it doesn't make sense to have a third vehicle.
