You need to get into both and play with the toys then drive them. A vehicle you LIKE is worth a few bucks if one were to randomly happen to need an extra repair.
However I am baffled why you need a $7K5 single cab pickup to drive 5 mi to work with no towing, but at least the short commute means fuel economy isn't as important.
I'd sooner get an F150, maybe Silverado, V8, because the support community of people who really know their stuff instead of stating "it's XYZ so take it to a dealer", and greater low cost part support including junkyard parts.
IF I absolutely had to pick between these two, I'd go with the Dodge. The Nissan is eliminated because there's no way I'd pay $7K5 for a 10 y/o 115K mi base model, single cab pickup. However it seems strange to consider it a base model with the 5.6L.
I would keep looking. Patience is a virtue. If you must get a vehicle N O W, anything will get you 5 mi to work, get some $1500 beater to buy some time till the right vehicle comes along, then you can turn around and sell for about what you paid for it, maybe even more if you clean it up, and not have to carry full insurance coverage, so tax and fees wash out to no financial loss.
