The above people are trying to help you. I have a 5x10 tilt utility trailer. From the factory, the axle was too far forward. It tilted like a dream, however, I couldn’t go over 53mph without it going line to line, with any weight on it. I moved the axle to the rear some, can now haul whatever I want, at any speed, with no “wagging the tail”.
Look online, plenty of info for axle placement. Rednecktrailers.com used to have an axle placement guide on their site.
For the bunks, as an alternative, remove the carpet - keep the pt wood. Put on a solid surface, of some sort, to separate the pt wood and boat bottom.
Some ideas -
- get a pvc fence post sleeve, rip it in half, secure to the bunks.
- look into commercially specific products . Such as caliber boat bunk covers, or gator back bunk covers. These are two that come to mind.
I’ve done both the pvc sleeve covers, and put gatorbacks on previous boats. Both did the intended job. As, or more importantly, removing the carpet will allow the bunks to dry in no time, thus, greatly extending the life of the bunks. Yes, you can remove the “bottom” layer of carpet, the problem is the rest of the carpet is still holding water.
A positive to the Gatorbacks (maybe others by now), if you get the clear ones, you can route a groove in the boards for led strips, put the leds on a switch, have lights to make it easier to load at night. Look up boat trailer runway lights for ideas. I did this on previous boat.
