which is what i was concerned about, which really isn't a big deal. I wish i knew the WMS distance on the axle of the HF trailer.

I think he best plan of action is to get the trailer, then if i have to (and probably should) get a new axle, then get the tub

How much should i pay for one of those?

The WMS distance on the 1720-lb. capacity HF trailer is 56.5" and the bolt circle is 5-on-4.5, same as the TJ and YJ Wranglers.

This is a shortened/strengthened HF frame running Jeep Moab wheels with 31" tires, here's a photo before the tub was installed:

Thats some great information, and some good links, thanks. I think you did a great job designing all that stuff. But i really like youre yellow trailer with the custom frame you made, over the harbor freight based ones (theyre still great though), Im really starting to lean to toward a custom frame. I wanna try and keep the jeeps axles and the trailers axles the same width.

Since its winter still where i am, and maybe when it warms up above 9 degrees, Im gunna start with building a custom frame.

Ive been given a lot of time to research and design. And reading though jscherb's many pages of information on this site and others has helped a lot, so thank you again

While continuing to R+D for ideas on this project, i cam across Coil spring trailers. This was what i kinda wanted to do in the first place to match the jeep but it seemed like to much effort.

Is trying to make it a coil spring trailer worth the extra time and effort, and probably money?
or should i just stick with leaf springs

between the girl friend (now ex hahah) and a killer price on a motorcycle i couldn't pass up. i havent. With summer over, and being back at school, i have no where to work on it. so its been set back. Life isnt cheap either haha. But this gives me more time to perfect my design i guess!

Any update on yours?! would love to hear about it and see it!

Leaf springs will ride stiff & bouncy when unloaded. But, a more fancy suspension can be a very big waste of time depending how you set it up.

Assuming you go with solid axles, you can do radius arms, but you'll need to build a track bar. You can do away with the track bar by running a wishbone 3-link or upper triangulated 4-link. Alternatively, you could go independent suspension with an dual A-arm/wishbone setup & individual axle stubs.

I looked at all that and it adds SIGNIFICANT cost. The suspension can easily become the most expensive part of the trailer. There's even a trailer build thread on JeepForum setup with an airbags + upper tri 4-link using adjustable Currie JJ control arms.

The question I ask with that is why? what are you accomplishing? It isn't suspension flex, because all the "flex" or articulation occurs at the hitch with the vehicle. Independent suspension on the trailer can be used to level the trailer on an uneven surface...or maybe you should just pick a better camping spot. The only other thing you'll gain in the trailer with fancy suspension is a better ride - but you're not personally riding in the trailer....so who's going to care?

Simplicity is calling my name. You have hit all the options, very nice, thanks!
The reason i asked was to try and keep it all constant with my jeep, hence all the trouble with the tub, otherwise i would just go by some boring trailer. Ive seen them built with the rear end jeep frames, springs and axles.

Set up, and tweaking of a leaf spring suspension is more under my skill list at the moment. (that and money haha) Plus adjustment of ride height if i wanted to lift it, that would be simpler as well.

all the time that it would take to make the some of those set-ups work with the 3 link, or 4 link suspensions seems outrageous. the time in, wouldnt be worth the reward out, as you stated in your last bit. makes sense. and im not trying to get a trailer to flex on rocks.

Most of the time in projects, i just jump in and deal with problems as they occur, that gets real expensive real quick. Im glad i haven't done that on this one yet. Getting as much info first is a better way to go. so Thank you again!

It's hard to get much simpler than assembling a Harbor Freight frame kit. And they work just fine off-road, the one pictured below is on an HF frame and is running 35's (it's got an upgraded axle :))...



Here are some links to info on modifying the HF frame:

Modifying the trailer to fit under a Jeep-tub trailer like the one above: Building a stronger 4'x4' frame out of a 4'x8' Harbor Freight frame

Modifying the frame to fit under a military-style trailer: http://dinoot.com/MSer-HF-frame.pdf

Upgrading from the "slipper" springs in the HF kit to shackle springs: Replacing noisy Harbor Freight Slipper Springs

Fitting Jeep wheels on typical trailer hubs: Fitting Jeep factory wheels on typical trailer hubs

Wider axle options for the HF frame: Wider axle options for a Harbor Freight 94564 trailer

All of this info and more can be found at the Trailer Adventuring Forum at Tventuring - Trailers.

Both the black Jeep-tub trailer and the fiberglass military replica trailer pictured below are built on Harbor Freight frames:

I actually just stumble back on their website, strange how the internet gets you places. and i must say, i like the new look of the page. they really made it more functional and way more helpful than its previous style. That and the forum they have created is pretty sweet. Helps to see the options, and styles laid out. And you are correct, it doesnt get much simpler than that. And while it might not be the most cost effective route, by the time i screw up 6 or seven times, this woulda been the way to go!

SO maybe once the weather starts warming up, and i move to my new house with a garage, I might be able to start this! FInally, fingers crossed.

Thanks again for all the information!
