2009 renegade 800x rear seat

I just pulled the trigger on a 2009 renegade 800x. Coming from a 2006 outlander 800 I can definitely feel a difference in the get up and go! What I’m looking to do to the bike is add a back rack and a rear seat( that I’ll make easily removable) for the wife since I promised her I would when I bought it haha, and also if want to install fender guard/foot pegs. I only seen one picture of a Rene with this done and was hoping maybe someone on here had some experience of were to buy the gear and how it holds up. Most back racks only seem to hold 50lbs and the wife weighs a tad more than that.

My second item I need to install is a plow. I know Rene’s army made for it but I need it since I’m going to sell my outty. Any help with this would be great as well.
Thanks
