I am on my 4th Ram....had a couple of 1/2 tons, went to a 3/4 ton for towing a 5th wheel, and just bought another 2017 1500. I always look at the other brands, but the value and ride seems to be the best to me with the Ram.
I've had only hemi engines, though I did have a 2000 with a 5.9 v8.
I have never had an issue with any of them, except my 3/4 ton whistling when the A/C was on, but the dealer fixed it.
I generally get around 20-21 mpg, I tow up to 4500 pounds about 5-6 times a year. The hemi seems to love to spin when towing, and there is never an issue.
The only thing I don't like about my current truck is that I got the quad cab instead of the crew cab....it gave me a longer bed, but now I would rather have the inside room....oh well!
I had thought about a V6, but I'd rather have more engine than I need than need more engine than I have. The extra initial cost is not that bad, and the mpg is near the same.
My only real gripe is with the crappy goodyear tires. I just replaced mine at 23,000 miles and they were almost down to the wear bars....not good with winter coming. I went with Falken AT3's in the stock 275/60/20 size, and love them....quiet, smooth, and rugged.
I plan to go 150,000 miles and trade it in....probably for another Ram!!
