I made extended this to 16 ft.....2 bikes and fuel cans or coolers and gear...extra room is always useful....

 

Why don't you just measure your 4wheelers? Get each one's weight, do a little math, and figure out where the axle needs to be to give you the right tongue weight, then go trailer shopping.

 

In order to haul 2 larger machines in-line, you're going to need at LEAST a 12' deck. I have a 7' x 11' deck that I haul 3 mid-size machines on cross ways, but cross loading is kind of a hassle.

 

It depends just what kind of trailer you want. If you want to stick with a utility trailer get atleast a 12ft deck. your other option is a deck over trailer with either a tilt bed or a ramp. If you go with a deck over, 10ft is plenty long. Alot of deck over trailers are aluminum and could save you a little weight if that is a concern for you.

 

I friggin love that setup! that's kinda what I want!

Were headed out next weekend to go riding. thanks yall for your input were gonna go get us a grizzly 700 I think and then as suggested measure the two together and add a foot or two for a little space.
A question for those more experienced. Tongue weight? do yall put your heavier atv up front or do you think it doesn't really matter with the lighter weight of the atvs compared to heavier loaded trailers. I know when I load trailers at work we dont worry too much but those are loaded with aircraft parts. Usually not too heavy lol

 

 

I had a 7x14' single axle to haul a Honda Rancher and a Kawasaki Prairie. Both fit in tandem with some room to spare.

 

 

I have a 6'x12'. It will hold a polaris 550 and an old yamaha 250. I can't put my brother in law's Grizzly 600 on there with the polaris.

Buy a 16' and be done with it.
