Going to be ordering a 2020 350HDXlt AWD.Rear Seat Delete to do our 2nd camper build.Have not decide what gear ratio to go with 373 or 410. Or last van had 331 gears and we were happy .We did a 15,000 mile Alaska trip pulling a 4x8 trailer with Harley and averaged 15.9 .Just looking for options with the new 10 speed trans.Thanks Mike
