So the little lady & I just got back from our weekend trip to the Wellsboro area with our friends. I had purchased a trailer hitch, a cooler rack & a TBag for the rack. We decided to try it this weekend so that we would know if there were any changes to be made or issues to deal with. I am happy...
I've had a Pakit Rak for about 7 years, and I also have no complaints. Well, maybe one niggling one - the little plastic 'chrome' strip they put around the edges of the tray is coming off and looks a little tacky. Other than that, very well made - both the rack and the bag. The bag may not look very fancy, but it sure is holding up well, including the zippers. I keep the rain cover on mine all the time it's on the bike just to keep the bag from getting too dusty. All in all, it's one of those things I bought that I remain very happy with.
It blocks the license plate from some angles (directly behind, and low), but I've certainly never been stopped for it. I've never heard of anyone being stopped for it. I did read a post once where someone made a colour copy of their plate, laminated it, and attached it to the back of their pack. I personally don't think it's a concern unless you're intending on piling something very large and tall on the rack.
@HS Driver like the guys said. The only time I was ever questioned was by a North Dakota border agent (who I still say was just bored and wanted someone to talk too). After a friendly debate, he conceded and made a great restaurant recommendation. Our set up is even taller than most because we use it to haul an extra luggage bag, not a cooler. Many times we have been passed on the road by law enforcement, been giving thumbs up, or waved at but never hassled.
I guess if it really bothers someone you could always attach the plate to the rack. That doesn't work for me, because when we get to the hotel, I pull the hitch pins and carry the entire rack into the room. So my plate would then not be on the bike.
