Lots depends on how that 2017 XLT was optioned
from the factory. Even if it has a hitch receiver you probably need to see the VIN-specific window sticker or build-sheet printout to
know if it has the
factory towing package (any Ford Dealer can provide that printout given the VIN).
2017 XLT's were available with either 2.3 or 3.5 engines (the 2.3 was an
option on the XLT!), with and without 4WD, with and without factory towing package. Attached towing limits page may be of interest
(from the online 2017 Explorer Owners Manual FYI).
