I'd like to chime in here although I do not own a Grey Wolf. This past weekend we went looking at new TT's. A couple of the Cherokee's had the rack mounted on the back of the unit and had the spare tire mounted on the rack. The sales person told us that the weight capacity of the rack was 200# which would include the spare tire. I had to ask him:"Then you are stating that this rack will only support maybe 120# or so"? Yep, he agreed. And another thing he stated: "It's not advisable to use this rack while traveling down the road, in other words don't put your ice cooler loaded with ice on the rack and travel down the road it will break it". So I had to ask: "Then what good is this d****d rack?" He just sort of shrugged and stated that is was something that a lot of campers had on them now. Hmmm, let's look at another unit then.
You can use it while towing but will prob drag the spare tire over every dip in the road. With spare on it hangs pretty low. I have never used it. Too much play and bouncing around in the mounts IMO. Plus by the time you relocate the spare you have wasted all the room you saved. Would be good for bikes I guess. Will prob use it for that when kids get bigger
We have th 2012 Cherokee 18RB with the back rack and use it for our bicycles. Have had no issues over the last 2 years. Think the weight sticker is something like 250 pounds carrying limit. Cannot check it right now, sitting between the garage and shed with snow everywhere.
