I am looking at getting a seed tender for next spring I would like some input on what manufacturers and models people have. Durability/maintanence/reliability. Etc. I am considering either a 40 ft model or a 20 ft mounted on a cab and chassis. There are a few manufacturers out there convey all, meridian, Dakota/cancade, and another manufacturer in the states I think called Norwood. They make a modular unit with poly tanks.
