Wow, thank you for the report. Hope you get to use it a lot and get all the fish you want to eat

If weight distribution on the trailer is not the best (wheels placed far back on the frame) look into if it is possible to move the wheel axel atatchment brackets towards the front of the trailer. You could also look into moving the towbar from the front of the trailer to what is now the rear end of it (turn trailer platform 180 and atatch towarm in the new front ) or combine the two. Maybe moving axel by using one old hole and drilling one new (looks like there are bolts there) helps, could be combined with moving the towbar. You are closest to the items so you are closest to decide.
