I would buy an older mixer wagon I have a Patz 240 we gave $1500 for at least 7 years ago found a gehl on craigslist my friend bought for $1800 then your feeding options are endless and they have scales on them. Of course you'd have to drive a tractor so the cowboy costume would need to be re-arranged.
It is not hard to put a small gasoline engine ( about 25 HP ) on the tounge and a 4 to 1 reducing gearbox, electric start and electric clutch and then you can do it all with your pick-up
