So your electric-pump is connected to the trailer-power? I assume you upgraded the wire-size, I don't think I'd want mine on my truck battery b/c they stay too warm under the hood which causes premature-damage. I wonder how much lead-acid storage onboard the trailer would be needed to do your 100-250 acres per day. Getting rid of smelly fuel & noise-pollution reduces quite a bit of stress, IMO.
Bear -- I am wondering if you would be open to a day in the life discussion. I am thinking about doing something similar and would like an unbiased view before reaching out to vendors.
