Hmm. I like the overall look, but worry about the 8-wide construcion fitting in when it's sitting alongside other city vehicles. Didn't the 7726 Coast Guard Truck with Speed Boat:http://www.brickset.com/detail/?Set=7726-1
have similar issues of size/scale?
Still, the pendular suspension looks cool, I wonder if it has springs or rubber bands or is free hanging.
I like the off road/ S&R type theme, It'd be cool to see a version of the 4WD with Horse Trailer turned into a search and rescue truck pulling a command/supply trailer.
