I always called a Blazer"wagon" when I register one here--then passenger plates can be used back when most "trucks" here were required to have commercial plates that costed more and had to be renewed yearly instead of every 2 years...but they changed the laws here a long time ago and now 1/2-3/4 tons with less than 5K GVW can use car plates...some states are picky and want exactly what the body emblems say listed on the reg,like "K-5 Blazer" ,other states like ours dont seem so anal--I have had several fleetside pickups that had varoius names under "model" like "Wideside" that never appeared anywhere on the truck--one Blazer I registered the RMV listed as "Utility" ...I'd call your RMV and see what they want it to be called,otherwise you may end up in a bind ...
