Trailer: Former 1978 Trillium 4500 owner
Posts: 47
Just wondering about Trillium rigs with cargo boxes added to the rear bumber. I just bolted a hitch receiver to the "box tube" bumber on the back on my 4500. I also have a "cargo tray" which gets inserted into the receiver. So the "tray" is rated for 500lbs... SOOOO what are your experiences with adding weight in this manner, and more specifically, how much weight?
Any input is welcome.
Thanks,
K

Not a good idea...too heavy...a bike is about enough weight.

Hi Kevin,

I had a receiver hitch mounted on the back of my 16' Scamp Deluxe. I bought an aluminum tray to go on the back. I carry a small generator (Yamaha 2500) and firewood back there. The main thing to watch is that your tongue weight will drop as the rear receiver hitch weight increases. I modified my tongue to carry two deep cycle 6 volt batteries, 5 gallons of gas, and a large plastic box for an inverter, solar controller, and misc storage. There are also two propane bottles up there. I planned the extra tongue weight to balance the stuff in the back (typically about 150 lbs for generator, tray, and firewood for me).

I added a receiver to the back of my Trill. The shop that did the welding for me added an "I" beam attached to the side rails about 6" forward of the bumper to strenghten the receiver mounting. I had a "Tilt-a-Rack" that weighed about 180 lbs and intended to put my 250 pound mobility scooter back there. Tried the set in the picture one time and about shookd the scooter to pieces. Trailer was light on the tongue with 430 lbs hanging off the rear bumper.

I had also added 30 inches to the tongue in the shape of a 30"X60" platform. The shop made it much heavier than I ever thougt it needed to be. Acually, they got the extension just a tad off square. Trailer wheels track just fine, but trailer is maybe 1/2 " akilter. With the tongue being so heavy from the extension, I thought it was too heavy to carry the scooter up front, so had mounted the box up front.

Put the Camping World slant lid treadplate cargo box (50 lbs) on the T-a-R and carried the scooter on the tongue. Works wonderfully.

Concidering removing Tilt-A_Rack and modifying one of those 2'X5' cargo carriers to carry the cargo box. I can save about 100 lbs off the back end that way.

I too have a Trillium 13 ft'er, and need to be able to haul a mobility scooter, weight unk. but is a good size 4-wheeler. I had planned on carrying it on the rear of the trailer on one of those platforms that go into the 2" hitch tube. from your description of your experience, this does not seem to be the best way to carry a scooter.

Did your problems go away when you carried your scooter on the tongue. Do you have a picture of the scooter mounted on the trailer tongue?

How long did you make your tongue, and what kind of material (steel) was used?

I now have the body of my trailer off the frame and the Trillium frame seemed to be made out of 3x2x1/8 box tubing. I was under the impression that it was thinner.

I plan on making a new frame, and was thinking of adding 30" to the rear of the trailer frame and a little over a foot to the front to place the spare tire and batt. there, thinking that would add the necessary tongue weight, that was in addition to the 2-20lb propane tanks.

What are your ( or anyone's) thoughts on this.

There was a gentleman at one og our glass egg meets a while back that had shown up with his 'modified' 13ft Boler.

He had cut the back end off, added two heavy duty lifts and a fold down ramp. The ramp was designed to ease loading/offloading of H/Capped scooters, motor bikes, etc.

He has visions of possibly marketing his conversion kit and was 'fishing' for some $$$ backing....

Doug, are you referring to Ray Howard? His design actually makes the back of the trailer a big top-hinged hatch.

Information is good. Lack of information is not so good, but misinformation is much worse. Check facts, and apply common sense liberally.

I think that if the egg shell is off the frame and there is to be frame work done anyway, a fresh start designed to carry the intended loads is a great idea.

My concerns:
  1. Even though the added front cargo area is a little further from the axle than the rear deck, it's hard to see how moving the tire there could be nearly enough to compensate for the huge load on the back.
  2. Adding massive objects to the ends of the trailer, even if they balance each other, makes the trailer more like a flywheel or pendulum (hard to get it started rotating, then hard to stop) and thus hurts control.
If a new frame is being built anyway, I think a front cargo deck is a much better idea.

Well I had a long reply all typed up and must have hit a wrong key, because I lost it. Here is a shortened version.

I think most of the shake and bounce I experienced was due to the extra foot to the platform and the semi floating platform of the Tilt-A-Rack. A solid platform tied to the frame would ride much better than the configuration I have.

Caryying the scooter on the tonge was no problem. I've got some pictures of the construction which I had done by a large welding shop near me. It will take me some time to resize and upload them. I don't know if I've got a picture of the finished project or not. I'll have to go out in the heat and take some pictures if I can't locate any.

Two lessons learned: one, make the extension an inch or two longer than what you think you need: two, make sure the extension is straight vertially and hoizontally with the rest of the trailer.

I agree with Brian about adding the length and weight to the front of the trailer vs the rear.
Also, there should be more of the trailer length in front of the axel as well as more of the weight. The physics of leverage will make problems for you if there is more length or weight to the rear of the axel.

I'll start on the pictures shortly, but probably won't finish tonight.

Thanks for your input. If it wasn't for this forum I wouldn't be doing what I'm doing and what I would have done would have been a disaster.

If it wasn't for this input I would have built the mobility scooter carrier on the back of the Tril. and now I would agree with you the tongue weight would be a problem. I will post this a a question.

I'm surprised I don't have pictures with the tread plate on. I'll take some tomorrow evening. The base of the platform is stainless steel tread plate. Then I have a ramp that is carried vertically that attaches with the two large knobs you may have noticed. The ramp piece is aluminium tread plate reinforced with square alluminium tubing. It's still lighter than a single piece of stainless would be. I decided to carry the ramp in front to shield the scooter or whatever I was carrying from the rocks my truck likes to throw. I cover the scotter with a cheap barbque cover and a cargo net. Cargo net keeps the BBQ cover from being whipped to pieces by the wind buffet.

If it's not too hot tomorrow, I'll set it all up for loading and how it travels and take pictures.
