I pull a Uni-Go one wheel trailer (pic available in gallery)  Capacity is much smaller than big two wheel trailers but it pulls like a dream.  Done Skyline Drive, Blue Ridge Parkway, etc. riding double and loaded to gills and only notice it at slow speeds and when braking but nothing drastic.  Hardest part of whole project was getting bike wired up with trailer and isolater.

Let me start out by saying a few basic points to keep in mind: 1) nothing is better than specific purpose built equipment and 2) you get what you pay for.

I've been pulling trialers for over 20 years. I started when I was in my early 20's and had my first Goldwing. I found a painted to match Bushtec trailer for a steel and have never looked back.

A trailer that is built specifically to be puller by a motorcycle is worth it's weight in gold. Not really but you know what I mean. It's suspension, it's empty weight, is carrying capacity, and it's composition all make for a perfect towing experiencel.

With that being said, there are a bunch of trailers out there. A few have already been shown on this thread. Some better than others but it will come down to you and what you want and are comfortable with.

I will tell you of my specific experience. I'll start out by blowing your mind and say that I spend over 6k for a trailer. My latest I will have almost 9k into it when it's all said and done. I use the hell out of them and I have ZERO concerns about loading it up to it's maximum ability.

I've had 4 Bushtec trailers over the years. I will never look anywhere else for one....never. I personally believe they are truly the best made bike trailer anywhere in the world. They are so well built that they (Bushtec) claim that if they every bounce you'll get your money back. I'm paraphrasing but you get the meaning.

Fiberglass is king but takes more work to build. Lightweight and durable. My current model is the Entourage. It's about 125lbs empty and has a 350lb GWR. That's a lot of stuff you can cary. I figure I have 200 lbs to play with because I also fill up the cooler and drinks/ice can weigh a bunch more than expected.

I filled one of my trailers to what I expect was MAX. You can read about that here

You can read that but in a nutshell, I went to Sam's Club and "if it fits in the cart, it will fit in the trailer."� Think about that a minute..

Let's say I've weighed it down to it's max.  It's pulling 350 lbs.  That really isn't as much as it sounds.  I've seen bikes with that much weight sitting on the back seat alone

On any bike pullling one of these trailers, you'll never feel the trailer other than by pure weight.  Never feel it over bumps (even railroad tracks) or in the turns.  NEVER. It's so easy to forget it's there. Only during accelleration or braking do you feel it.  It's just weight. Bike's today can handle it with the big dual/quad ABS pucks and such.  If you rememver it's there you'll never have an "oh shit" moment.

My current setup is in it's final stages of paint but it's still a Bushtec and like that above, I've loaded the crap out it. My wife rides her own Victory so between the 3 of us (her, my kid, and I) we can pack as if we are going away for weeks in the SUV.  Whatever you want to bring,  just bring it!

3 people worth of gear, tools, oil and fluids etc, cleaning kits, remote control toys (keep it clean) etc. Just bring it.

When I do my solo rides I will more than likely bring it along.  Just mildly loaded it will weigh like 200 lbs. Like a large passenger. It has the lowest rolling resisitance of any trailer built anywhere (Bushtec claim). Even fully loaded I can move it around by hand like it's floating.

Got to get back to work.  I'll add more I'm sure in a bit.  Idon't want to loose what I've done thus far.

I want to touch on suspension and coupling in a bit.

I haven't touched on one of your questions. Brakes. No, you won't find any bike trailers with brakes. They will never be heavy enough to need them. I believe trailers with a GVWR of 2500lbs require them??? Plus, if they had them then some sort of brake controller would be needed. What a nightmare that would be.

Ok, suspensions. There are torsion suspensions, leaf springs, air suspension, single axle, independent suspensions. If you can think it they're out there.

I've seen going down the road trailers behind bikes that seem very bouncy. stiff suspension or very hard tires. To me, not safe and comfortable. Not to mention the contents of the trailer are going to feel it too.

I've seen the single tire ones like mentioned earlier. They seem good. I haven't used one or looked closely at them but my initial thoughts are "they don't seem to be able to hold much". I can't speak fact here but they really aren't very big.

What I am sucn an advacote for is the independant air suspension. Suplimented by actual motorcycle tires/wheels and an functional sway bar. I am of course speaking of the Bushtec.

You can pick one of these up and drop them from a matter of feet and the suspension just sucks up the impact. They ride so smooth that even on washboard dirt roads (I've actually been on a 30 mile stretch of it) they are invisible to the feel and not even so much as a rattle. I mean real washboard roads.

Coupling is another thing to consider. There are only two that I am aware of or see out there. The traditional ball type and the pin type.

No suprise here that I am a fan of the pin type. A pin on the hitch that mates with a hiem joint on the trailer. This allows for vibration free/solid conection that allows for 100% unrestricted rotation of the trailer. That trailer could be flipped and rotated and the only thing you'd feel is the tug of it (I know this as I am very experienced with offroading with trailers. I have had one flip while offroading).

Pulling a trailer behind your motorcylce opens up a whole new experience. Unknown before distances, remoteness, and comfort. If the trailer really wasn't noticed behind you, and you could take a months worth of clothing, spare gas, parts, peices, helmets, SCUBA gear, real camping gear, skydiving equipment, etc, what could you do? Really opens things up.
