During my recent 3 week trip to Florida, my Curt Mfg Q16 had a small problem, where the indicator to show the hitch was latched, ended up being broken. Of course, at first it was sort of worrisome, that it wasn't latching up all the way, but the little indicator was sort of stuck 1/2 between the yellow 'latching' and the green, latched setting. It was very obvious the latch was fully engaged, and I tested it several times with a 'tug test', and then towed all the way home, about 1500 miles without an issue.
Now the Curt Q16 has a "Limited Lifetime" warranty, so when I got home, I took a look at the little indicator, and I could see it really was nothing but a round plastic piece, which had a little pin that broke out of the plastic. I figured that Curt would send me a replacement indicator piece, and I would change it out, and be all set. However, the service tech at Curt said I couldn't change it myself, since there were torque setting which aren't published, so they sent an entire new hitch. The only odd situation was I have the RAM mounting puck system, and when I ordered my hitch, it was shipped by truck since it was too heavy for FedEx. The hitch assembly I got was just for a regular fifthwheel frame mount, so it probably was light enough for FedEx, however, the FedEx guy said, you have to take that off the truck, it's too heavy for them. I lifted it off, and sent him on his way. I just replaced the head/box assembly, and packed it up and dropped it off at the local FedEx location to go back with a 'call-tag' they had included with the replacement.
Overall, they provided great service,
the replacement hitch arrived in 3 days, if somewhat a pain because I had to take all of the assembly apart, and put it back together. The worse part is I didn't have the hitch mounted in the truck when I reassembled it, so I'm certain I'll have to loosen all the bolts to remount the hitch, and then torque the bolts back to required settings.
