definitely a Silverado. the tundra is more of a luxury truck, and is not as reliable when towing heavy weight. the dodge 1500 would also be a good pick, but the suspension is typically not as reliable as a Silverado. the only reason that the F-150 is the best selling truck of all time is because the F-series truck is one of the only mass produced trucks that ford has every made. ford has been manufacturing the F-series truck since 1948. Chevy has only been manufacturing the Silverado since 1999. before the Silverado, Chevy manufactured the Custom Deluxe. but ever since 2001, the Chevy Silverado has been outselling the F-150 by a margin of 3,000+ vehicles sold each year. also, Chevy Silverados retain their value for a much longer time than the F-150. hope this helps.
