    Question Aluminum Utility Trailer

    I am about to start on a utility trailer made from aluminum and am looking for opinions on whether im on the the right track or not. The trailer will be 16' long and 6'10" wide. Im going to use 2x5x1/8" tubing for the main frame and the tongue which will be wrapped under the frame. The x members will be 3" channel 3/16". I was planning on spacing the x members every 16" oc. Its just going to be a general purpose trailer hauling anything from zero turn mowers to utv to possibly even light vehicles. Does this sound like im on the right track?

    Cool

    Yes no and maybe. I would use heavier tube for the side rails just my thought. And what are you going to weld it with?...Bob

    I would consider going alittle heavier on the tubing just incase.

    From the vantage point of having seen and repaired a TON of broken aluminum junk on trucks and trailers I would strongly advise you to use steel instead of aluminum. You can cycle steel Waaaay more times than you can cycle aluminum. If you are insistent on making the error of using aluminum for a utility trailer, then pony up the cash and get some bigger heavier tubing.

    I realize that steel would be the stronger option but I have just always wanted to build one from aluminum. I also forgot to mention that I would be using 2x2x1/8" tubing for the top railing so that should add some extra strength. I will be welding the project with the spool gun on the 212 or dare I say a Lincoln power mig 350 with a push pull gun.

    I would be looking at a commercial built one to copy at the minimum.

    Cool

    I still would use thicker tubing where the cross members weld in. I fixed a steel trailer this summer that was built similar to what you are describing that the 1/8" wall tube didn't hold up and caused all kinds of problems. One the spring hangers pushed thru the tube and a few cross members pulled chunks of tube out. The guy was a landscaper and i am sure the trailer was beat on a daily basis. I have some alum horse trailer pics someplace that pretty much fell apart on the frame. One it was a totally bad design and two they didn't use enough aluminum...Bob
