I liked my tow-n-go mirrors until I lost one on my last trip. I have just purchased a set of McKesh (McKesh.com) they are very expensive but I hear they are very good.
I too like the Tow-n-see. Only purchase the convex one as the flat one is practically unusable.
I recently purchased a Covex mirror similar to the Tow-n-see. It uses 3 suction cups to secure it to your vehicle's mirror instead of the single suction cup that Tow-n-see uses, so it is a little more secure. The stem is a little larger in diameter to dampen vibrations and it is a little longer too. Though convex, it has less curvature than the Tow-n-see, making it a good compromise between a flat and a convex design. I purchased it in May from Dyers RV for $18.98, however I now see it in their online catalog for $165.66, which I assume is a misprint.
If you cannot see over the trailer with the inside rear view mirror and cannot see what is behind you with the outside mirrors you need extended mirrors. They are of some help in seeing back. I have the ones with the rubber straps that attach to the regular mirrors. They work OK and have always stayed on. Just make sure you keep them tight. I do not need them when towing the Fleetwood popup, but they are a must with the HiLo.
I think that there are state laws requiring you to have mirrors that extend far enough to see past the trailer.

you have 2002 Cherokee? you must mean a Grand (not important, just curious)
I use the Tow-n-see also on both my Unlimited and '01 Cherokee. I found they took a little getting used to because the suction cup covers a fair bit of your main mirror... and I agree with sushidog regarding the non-convex being pretty much useless. I'm going to get another convex for the driver's side.
IMO, the McKesh mirrors are by far superior to the Tow-n-see and I intend to upgrade someday, but the Tow-n-see are better than nothing.
