The 1:1 camper is originally Neptune, don't know if its staying or different blue.
Steelies almost always look good, especially if the backs have been widened. 8 spokes look good too.
Swing arm shouldn't be all that difficult to muster if you wanted it. Although I guess size is the limitation. It wouldn't give you a diff but using something like a losi micro trans sideways so you have a wheel per drive shaft would give independent rear on a swing axle... could even set it up with "real men drive on the sidewall" wicked camber .... just stirring the pot a bit more
