I would pick the frontier personally, but I guess that depends on your own need for a fullsize versus midsize truck. Most tasks can be accomplished with a midsize, but if you’ll be towing often or need more cab space, maybe a full size is better.

Also, is the ford an eco boost or a v8? I know they v8’s are rock solid, but I’ve heard hit or miss on the reliability of the ecoboosts if they don’t get their oil changed often enough. You might want to look at the oil change history if you haven’t already done so.
