For added detail you should shave the door handles off the AMT cab and use the seperate handles from the F-350.
Great idea, and already done.
The Modelhaus dually wheels are modified Chevy duallie snapper/promo from the early '90s. They are pretty generic, so they will work just fine here. Their tires are Goodyear Wrangler ATs, identical to the Explorer kit tires, but with an enlarged I.D. to fit the wheels. Cast in black rubber, and nice. Why am I not using the Monogram duallie wheels? They are too small for 1:24, even a bit on the small side in 1:25, and the Modelhaus wheels are about 1.5mm larger, so they have the right look.
One thing they do lack is lug nut detail, and something had to be done about that. I went to my local model train shop and asked the guy if he had plastic nuts molded on a tree, and he took me to a display of metal hardware, all too big. He said he didn't have the plastic nuts, so I looked around and found them on a wall about ten feet away.
They had several sizes, so I picked these. Just right I think, and for three bucks, you get ninety six of them. You'll be in lug nuts for quite some time.
I drilled the wheels and tried a lug in one:
I then cut all four wheels down to faces to use the Monogram wheel backs so the truck would roll.
