I feel like the TRD Pro kinda like I feel about the FJ Cruiser. It's fine. Pretty good for what it is, but wish it was something else I really want.
The FJ Cruiser should have been a 4 door wrangler with Toyota quality. Not a 4runner coupe. As an FJ40 owner, I really really really wanted a new FJ40 replacement that could be a ligit daily driver.
The TRD pro could have been a perfect balance between the Rubicon and Raptor. Either use a 4.6L v8 or the older 4.0L with a blower. 8 speed auto. I would go so far as to say keep the same shocks/springs, but add KDSS. Add a full set of skids just like the front skid - it's perfect, just give us more. And give us a better roll cage inside that's integrated to the roof structure so you can put a heavy duty roof rack up there that has better structure. Maybe do something a little different like two rear bucket seats and a cooler in between. If you want to go just a little further, toss in 8.7" front diff from the land Cruiser / Tundra so the drivetrain is ready for 35/7" tires.
This could be almost entirely off the shelf parts that are already being manufactured, and would IMO sell as fast as you could spit them out at $50k.
