The Mazda and Nissan are manual you don't want that, auto leaves them for dead when towing, 1st gear is usually too high so most slip the clutch, not good, auto's used properly just perform better, though many folks have no idea how to use one...........until these new boxes I never liked them in trucks or cars but do now......
The 2013 Ford looks good, I was originally going to have boxes like that with the middle section caged for fuel, genny etc but found the shed was cheaper in the long run.....2011 Ford standard suspension both seem good for age................
