I googled and searched forums for info on adding the TRV passenger seat to back of my 2011 MP 1000 and couldn't find any solid answers. Then I called two dealerships and asked the parts people if it was possible to piece it together since the frames and everything are basically identical. Both dealers said no. Well.....It's very possible. I just compared the parts diagrams for the TRV/Diesel models with the MP 1000 and it looked the same to me so I ordered the rear TRV rear rack frame on eBay, L & R rear fender supports and the TRV seat kit off of Country Cat, and the L&R rear TRV footwells off ebay. BAM! Fit like a glove. Trying to load pics of my rig on here for you to see...
