The hutch mod has nothin to do with the big nozzle. Also the big nozzle will fit in all the trucks it just doesn't vent well enough to let you fill it wide open and then kicks of at like 25 gallons and you have to baby the next 3-4 gallons in there.
I've heard some people complain that they had to cut the plate out in the fill receptacle because the big nozzles didn't fit.....mine does without issue....just saying that some have reported the issue.
