If you’re gonna blow fork seals on trailer, they’re gonna blow when you’re riding! Yea, 2-3” is about 40-60% travel and it’s not going anywhere. I’ve found this amount through watching the straps when hitting bumps. Adjusted so they weren’t completely slack In middle of pothole and then get slapped tight when bike rebounds. I’d rather lose some form seals than entire bike, which I’ve seen too many other people do.
