The only things he stocks regularly are things made by other companies like Ofna, hence the diff kits and supershocks. All these things sell for tons on eBay. If Robin doesn't change things or come up with new products, I don't see how UE can survive. I hope I am wrong, but I know a lot of people who don't build Supermaxxes anymore because they are worried about the availability of replacement parts. Also, the Maxx design is getting very dated so supporting new vehicles is essential.
