Vintage 1981 Milton Bradley Big Trak & Transport Trailer Electronic Truck WORKS! This has got to be one of the coolest toys ever. Literally just spent 30 minutes playing with it. Im to young to have had one of these as a kid but it seems like everything wirks perfectly fine. It makes all it's noises, fires, the light flashes, goes forward, backward and turns albeit not great but im fairly certain they never did. Comes with the instruction manual which you will probably definitely n...eed at least for the first few minutes as well as a couple of extra decals as seen in the photos. This item takes a crazy amount of batteries, total of 5 D size and 1 9 volt which you will need to supply on your own accord. I am not sure if the transport is supposed to be able to dump or not but i can't figure out how to do it as the directions appear to only be for the big trak. I am unsure if that feature works or if it is even supposed to do that but you as the potential buyer has been informed of this prior to purchase. Condition is Used. Shipped with USPS Priority Mail.
