single or dual axle trailer?

Probably two. BUT. It depends on the trailer design and the GVWR. It may have one 7,000# axle or two 3,500# axles and have essentially the same rating. Or it might have two 5,000# axles and have much higher rating. Things are rarely as simple as black and white.

I have a 15 foot TT single axle and no issues with tracking or anything else. However, if I was going to that length I would feel more comfortable with a dual. A blow out on a sub 3k lb trailer like mine would probably be more manageable than a heavier longer trailer TT.

I thought I wanted a single axle TT, but I got a TT I wanted and it had tandem axles. More cargo capacity with not much more weight.

It creaked and groaned until I upgraded the suspension, with wet bolts, bronze bushings and Dexter E-Z lift equillizer.

Try to negotiate this upgrade in the purchase price.

I would never get a single one at that length.
If you had a blow out going 60 you would be all over the road.

I have had two separate ones with tandems, and the second wheel kept the trailer as straight as an arrow.

You will find a dual axle trailer much easier to back and maneuver in addition to the many good reasons listed above to own one.

:C

my vote is for dual!

my 3500# 20ft KZ is single axle. when something goes wrong suspension or tire wise, it's an instant critical problem, there's no limping with a single axle'd trailer.

I would think most 21-25 ft trailers would be dual axle.

YES.......

Easy to overload any trailer as many folks seem to do.....

But with dual axle weight is shared, loss of tire (flat/bad bearing etc) is NOT as bad, dual axles are more stable etc.

BUT trailer options MAY be less if you ONLY look at dual axles

Many of my trailers were single axle units...and we enjoyed them ALL

My vote is for dual axle...Always felt better with more points of contact on the ground. Our first trailer was single axle. I always felt like it was pulling one way or another when towing. It could of been the way we had it loaded? Didn't know bunch back then.
