Amazon.comYou could use a 5x8 dump trailer and weld on 2 grain gates on the tailgate. Make some wood sideboards and cover it with a heavy duty tarp.
I'm glad you mentioned mold / humidity. It happens, even up here in central Iowa. We had about a third of a pickup load of hog feed turn moldy in a good, tight, 10x10 portable wood shed.When I'm feeding I use about 1000 lbs of feed a week. I tried to use a feed wagon similar to what you are thinking about that held 5000 lbs. By the time I was getting to the end of the load the feed would start getting moldy and clumped together. Ended up costing more in wasted feed and time to clean out the wagon than the savings.
Also check around on your feed prices. I'm not that far from you in Wharton. 14% all stock is $10.50 per 50lbs at the feed store. There is another feed store about 10 more miles from me that is usually cheaper, but I haven't been there in a while. Don't buy your feed at Atwoods or Tractor Supply.
