You are buying this truck for towing. So test it towing.
The reason this is important is this. Back in 2011-2012 some interesting info came out.
Only the GM was dynoed by the stringent SAE standards.. This explained why GM was easily winning all the towing tests back then. With todays electronics it is easy to program a truck to make more power briefly to get a good dyno number, and then reduce the power to a level it can sustain. That is what was happening back then. Think peak HP/TQ vs continuous. The high peak powered truck may feel really powerful when empty, but put a load on it and climb a hill and the truth will become evident. No idea it this applies to todays trucks, but the Dmax is still the same. There haven't been any tests yet that can be even remotely considered independent, so I am withholding judgement as of now
