Very nicely done! (needs more sponsor stickers though ;o)
As a suggestion - you might not want to consider it immediately, but I recently converted my RWD HiLux to 4x4, and as you're probably aware you can buy powered front axles for the Tamiya 1/14th scale trucks (from Lesu and similar) - so it might be worth converting it to 4x4 at some point with a suitable transfer case? fwiw. I imagine a faster (eg 550 12t) motor would give it some proper Dakar speed too - although I would say that your running video makes it look very scale realistic already in that regard.
Top job!
