Agree with the -4. I installed an "XL" baseplate on our Frontier. It's well-designed and if anything it's over-built. Not that that's a bad thing when you're trying to keep a ton or two in line back where you can't see the nitty gritty of what it's doing. Still, it looks like something I'd build in my garage. The older RM systems are so awkward to remove that most owners don't. In a campground, their cars look like they have snowplow frames on them and the BlueOx owners' cars look like they were driven in by visitors. RM's new stuff levels that playing field.
From what I've seen, read, and heard from a good RV shop, the RM stuff is the best of the popular brands.
Good choice. Put'er on and GO. But by all means with a Coach-Mounted Tow Bar. I went Toad-Mounted and dearly wish I had not.
