I will be in the market for a tonneau eventually, as that's one thing I would say I'm most disappointed in with my truck, if there is one... The Limited comes with a tonneau from the factory, but the previous owner removed it for whatever reason. So, missing a factory option, but it was too good of a deal to pass on just for that one thing. So, while it's not an immediate need, it's something that's on my radar eventually...
That's an interesting concept with the bed rug too. Not sure I would get much benefit out of it, but definitely wouldn't have guessed it was thick enough to wear you can't feel the actual bed through it.
