Anyone ever put a tag axle or an axle you could release pressure on via airbags or some type of cam mechanism so tight turns are easier and more support on open roads. I'm thinking about adding an axle. Trailer would then be quad axle

BigSilverCat did. Have fun.

I'm speechless 😮😮🤤🤤🤤🤤🤤

What's the reason for the 4th?

Didnt like the way my boat was hanging way off the back of the main frame of trailer. It has long very heavy cypress bunks but it' still wood. I think its a bad situation and doesnt provide enough support to the hull over long period. I moved the boat up about 14 inches and I have about 6 more I can go. Looks much better now and trailers better. Adding another tag axle will add more support , have less trailer flex ,less tongue wieght and track even better. My 320 had triple axle which i thought was just right. This boat is 9 ft longer. I realize a 4 axle trailer can really kill the tires on tight turns which is why im looking at tag axle. Leaf spring with air bag. Tires would still be on the ground without much force until air bags are pressurized. Also going to add more bunks, bow catch and guides so I can drive it on trailer without a miss. Like pool ball in the pocket.

The way it sat when I bought it

What size axles are under the trailer now? they look like 6 lug 5200lb.
If it was me I'd rather have a new trailer built with 3 7k axles rather than add a 4th. that trailer looks small for the boat anyways IMO

If I was going to use that trailer I'd refit it with three 7K's and move them as far aft as possible.

Thats a thought but I still want the extra support. Boat is 9000 dry and I did move boat forward 14" I think those are 5000 each I'll have to check

Here is a closer pic 6 lug wheels. I got rid of one of those cheesey roller guides up front and added 2 6ft long bunks up front until I can get to the rest of it
