Dang, they're multiplyin;
Then I added some angle iron as a tire stop;
They work pretty good. The pickup frontend swivels around without too much effort at all. I will put the rear dollies under it after I get it in the garage;
I was slightly concerned that the 1/8" steel would bend in the middle and require a gusset across it, but no sign of that happening.
I also designed them so they would hold up a jackstand;
I will use a ratchet strap to strap the jackstand to the dolly so it wont tend to tip over if I push it sideways. I may just go up over the frame rail with another ratchet strap and strap the dolly and all to the frame if I use the jackstands like this and work under the truck. You cant be TOO safe when it comes to tons of steel over your body;
It took me about a day to make them. I got the casters for pretty much nothing, and had the steel laying around, so the total cost is exactly what I had in mind.
