Expedition vs Suburban

Towing, the 3.5 EcoBoost will easily out perform the Chevy 6.0 while also providing much better loaded and unloaded mpg. The long wheel base of the Burb may make for a better towing experience though. IMHO you’re taking somewhat of a step back on either from a 3/4 ton series truck. Is a bed topper out of the question? If it’s for seating I understand your dilemma, but you’ll also loose some rear cargo area on the SUV with seating being used. Either way, with careful loading and cargo management, either SUV properly equipped should work. Just pay attention to payload ratings on both.
