Thinking about buying a "newer" truck - any advice?

I had a 2005 Ram 1500 r/c short bed 2wd with the 4.7. Bought it new, had it 5 years, put 60k on it, and did nothing but change oil, one set of plugs ( at about 40k ), and tires. I occasionally used it to pull a trailer with a car on it. The 4.7 that year only had about 230 hp, so it was no powerhouse but it did the job. The original plan was to drive it 10 years, but I foolishly priced it to someone and they bought it. I got $10k for it in 2010.

My present truck is a 2010 Ram 1500 r/c short bed 4wd with the hemi, towing package and 3.92 gears. I love this truck! I'm planning to keep it 20 years if possible. It now has 47k on it with no problems, just oil changes and an air filter, and tires. Remarkably, the 390 hp hemi with the low gears gets about 1 mpg better year around than the 4.7 did, probably due to the terrain around here. Tows great, too. The pic below shows it earning it's keep. Both truck beds are full of parts, too.

I actually did try out a new 2010 Ford before I bought this truck. It was a r/c short bed 4wd also. It might have had a bit smoother ride, and had a little more upscale trim to it, but it was 3k more. An older friend actually bought it after I test drove it. I'm sure glad I didn't buy it though, he had trans problems with it before it had 50k on it (and he didn't tow with it either). His fuel mileage also dropped to around 12 mpg and the dealer never could make it do any better. So he doesn't own it anymore..
