Got a truck gas station weight ticket on my 2018 C30, AC/Gen options. 1/4 diesel and 3/4 water. Fully packed for 10 day trip, food, cloths, linen, tools, etc.
Came in at 16,020 on the trailer.
Tongue was 650 lbs (have a receiver with a ball weight scale built in) and towed great on the triple. Wind and passing trucks has not much effect.
If the trailer is the one from EZ loader that I think it is, triple axle with 4 bunks, then its rated for 13,500 and has an empty weight of 3,000.
This means my boat weighs about 13,000 as packed/provisioned. Cutwater website says dry weight of 10,200. However, add 1,300 fuel/640 water=1,940 of liquid + 6x80lb batteries = 2,420 additional for wet weight. Add 500lb generator and a couple AC units, say 700 additional lbs. So, the boat should weigh wet, but empty mathematically should be about 13,200.
Actually, that is close to my actual weight of 13,000, but I'm missing 950 fuel and 160 water. I'd probably weigh about 14,110, full packed, provisioned, tools, etc.
As for the trailer....
So, 13,500 rating - 13,000 actual boat weight is only 500 lbs margin and I didn't have and additional 950lbs of fuel and 160 water!
The trailer is under spec'd in my opinion. I need to verify the model I have, but it has 225/75/15 tires at 2850 each.
That is 17,100 lbs of tire capacity. Not much excess capacity there either. However, I did find some G rated (14ply x 110psi) 225/75/15 tires rated for 3,490 each. This would bring the tires to 20,940 which is much better!
