So update after a lake day.
1.) I have hellwig helper springs on the truck. I towed a 5,000 lb tractor on a dual axle trailer last weekend with less issue than this boat trailer.
2.) I put new tires on the trailer half a mile after buying it. (original 7 year old tires looked wore out and I was not ready to trust them.)
2a) Discount tire has tried and failed three times to balance the tires. I have massive vibration at 60 mph. My wife started freaking out at it. They then also broke a stud taking the tires off the last time. They have referred me to a "trailer" store to get the stud replaced I will be inquiring there about a proper balance as I could not get the manager to accept that their machines were hub balancing the tires and trailer tires are not made to be hub balanced. Everytime they take a wheel off and put it back on the balancer it would give a different weight to be placed.
3.) I loaded the boat further back after the lake today. Prior (cleat to the bow roller). Today Roller touches the first "ridge" in the boat. ~3 inches further back is the cleat. The truck road sooo much easier, no dragging ass feeling. By the time I got home to a level spot to check the tongue weight the boat had moved forward half of the distance. (I had gone from 44" bow tip to tailgate to 47", closer to 46" when I measured). Tongue weight was 500 lbs by that time instead of 650#. The issue is that nothing but the bow stop holds the boat from sliding forward. All other straps pull forward on it. I had contemplated just adding two more straps to keep the boat where I want it. This seems like a bandaid and any sudden stop could cause the straps to fail and the boat smack the bow stop HARD.
4.) I have a vibration that I will discuss in another subforum as it pertains to my motor(s).
I really appreciate this scale, If I cannot get this figured out in the next week I will send it off as I can tell now what the truck rides like when the stop is right.
@Betik . There is a local craiglist add for an older 2008 all alluminum trailer for $2500 I've been eyeballing it hard. I just do not know if I can sell my current trailer for $1400 (galvanized mfi) or if I would end up owning two trailers which would cause my wife to lose her shit as this boat has been much more trouble than she was sold on.[link]

@Neutron I appreciate the link, that might be perfect. I can install that on my trailer and keep the stock bow stop/winch setup.
