triple axle trailer vs. double axle trailer
 

Is there a upside to have a double axle trailer with large tires compared to a triple axle trailer with smaller tires

Maybe the slight decrease is tire replacement costs and you will pay slightly more tolls in some places that charge per axle. Other then that no downside, I vote for triple axles.

triples, if ever your have a flat tire you can always keep rolling on the other. if dual axle, get a flat, and if you don't have a spare tire, you are done. so changing 6 tires on the long run is cheaper and less trouble than being stuck at night on the road with your child aboard,, trust me. I now have a triple, with 2 spare tires!

tandem dually

This topic has been covered before. Triple definately over a tandem. See this thread and my post in it below:

It depends on the size and weight of the boat.

You can easily have a 30 foot boat that I would much rather have a dual axel under then a tripple. Myco uses dual for most of thier stuff under 30 feet. I sized up all my stuff on my boat and I can get a blow out and still run no problem on one tire. My boat is 8500 pounds full of fuel plus the trailer. Each axel is rated for almost that and the tires are rated for close to that as well. So I guess we need more info :D

Tandem dually!

I have lost a inner tire and still pulled it 20 miles to rest area to throw the spair on.

I have two 10K HD axles and my tub is north of 13,000lbs

I find it easier to manuver then tripples also.

Ultimatley gooseneck tandem would be the best.

What size boat are you looking for a trailer for??

I have a triple axle trailer that is coming up for sale shortly

30' concept

Yes, tandem dually is the ticket. Triples can be tougher to turn in tight spots, but prefer it over a tandem(single wheels). Triples also seem to track better.
