I honestly think you already know the answer. Facts-
- You trust Toyota more than GM as a brand, personally.
- You have a bad taste in your mouth with your current 'devil'.
- You will be anxious/leery/edgy any time you tow with said current 'devil', because you know how it hath scorned you in the past.
If I were in your shoes in the above circumstances, I'd be buying the Tundra. Even if it's a somewhat basketcase, it can't be a ton worse than the one that's already bitten you. Peace of mind sometimes requires a change of scenery.
This is exactly my Sister's family's situation. They had a GMT800 "heavy half" with the 6.0L and 4L80E. They towed their 32' travel trailer with it. I have to preface this with the fact that neither my sister nor her husband have any vehicle knowledge at all, so they tend to defer maintenance out of ignorance. They're the type of people who drive something until things go very wrong and then find the most dubious ways of fixing it.
A quick story to drive that point home... they have a Ford Windstar with a bazillion miles on it. It had an oil leak that they didn't realize (despite the multiple oil stains on their driveway). One day the "low oil level" light came on. The next day it was gone, so they assumed that the oil fairy visited and they never checked the oil. Turns out, the dash bulb burnt out. They kept driving it (and my BIL actually slipped on some of the oil in the driveway and had to get surgery on his knee). He called me one day to say that it overheated and died and it had been making this tapping sound for a few days. Facepalm.
So when they decided to part ways with that Silverado and were considering a Tundra, I fully supported it, but I also told them - with a bit of subterfuge/psychology - that they needed to take advantage of Toyota dealers' free multi-point inspection service and to call me with questions after those appointments. They bought the Tundra which makes me happy that they have a vehicle with a better reliability history, but I can only hope that I've set them on a path of actually maintaining things.
They are already the type of people who go to the garage for oil changes, so my hope is that they have fewer repair issues by suggesting they go somewhere who will try to sell them something and then calling me to ask if it's actually needed.
Long story short.... if you're looking at ditching the Silverado, pull the trigger on the Tundra. If you were towing 12k, I might have a different suggestion, but a car trailer? Tundra. One of the things about this comparison is that your Silverado might have $500 repairs every year. Even if the Tundra had $5000 repairs ever ten years, that wins for me even though it's a financial equivalent. Having 10 years of not needing repairs is better than the 10x downtime.
