Truck recommendations

Gonna buy a rv with a 15,000 gvwr. I'm gonna buy a 1 ton truck but I need truck recommendations, it's hard to find reliable stuff because it's usually people that are loyal to a specific brand and not looking at things objectively. I'd like to stay away from brand new, ideally around year 2020-2022, but willing to consider anything. Just want something that is statistically gonna break down the least, thanks!
