Yes my 87 xtra cab long bed was a 2wd. I also have never seen one in 4x4. I do have an 86 turbo space cab 4x4 with a reg bed though.
I was at a friends house in the late 90s and a friend of his rolled up in a 94 extra cab long bed 4x4. After drooling over it they said he'd bought it from another friend who builds limosines. It was super clean and pretty cool.
You can go through life being scared of the possible, or you can have a little fun and tease the inevitable.
Give a man venison, he'll eat for a day. Teach a man to hunt Blacktail, he'll be frustrated for life!
