tailer size

[Airslot]

I have had both under my V. The single can do the job fine. The tandem will do it much better. I do a lot of trailering and like...love having that extra axle under the boat. Everything rides so much better. I also think its great spreading the load over 4 bearing sets as opposed to two.

I could go on, but the bottom line is it really depends on how you use the boat.
