I like these trailers a lot, thank you! There are a couple issues I've seen with the hay train: the first couple bales load hanging half off the front end, they don't support 220cm square bales, lastly, the loading trigger for the small trailer is hard to find and trigger. It would be great if there was an option for strobes on the back of trailers as well as an oversize sign that could be activated with simple IC or IC. Thanks, great stuff either way!
