Long Haul with boat

[Padraig]

Have hauled my 6,000 # boat before but this time it will be to Bolton Landing NY, about a 420 mile haul. I will be leaving it there for a engine rebuild and a few more added horses . I have filled up the DEF and have a spare 2.5 gallon container packed. I have read that hauling a load increases DEF use. Am I covered with a full tank and a spare? Driving a 2023 Suburban. Longest trip, till now has been 120 miles.

I don't tow and likely won't, but it seems to me that the additional DEF usage others have indicated is nowhere near what you are already prepared for. With a full DEF tank and a spare 2.5 gallon container, it seems like you should be perfectly fine outside of a malfuntion like an incorrect level reading (which I guess is possible).
