    Default Tung for trailer

    I would make the tung out of Retangle tubing 1 1/2 x 3 by 3/16 long ways for 2x2 by 1/8 Alum. I would not make it any less if anything, Little thicker wall on everything. But hey thats me 2 cents lol

    Ditto on that for sure. That is even too light for STEEL!!
    Is this a trailer you are gonna pull around behind a garden tractor, or behind a car on the highway??

    it is for the highway i was thinking it was to light but i want to make is as light as possible. Its for behind my Mini Cooper so weight is an issue it will mainly be used to hall a tool box or a few sheets of ply wood and some two by fours. i would make it out of steel but im sick of dealing with paint and rust. as my friend has with his trailer.

    So i updated the bill of materials with changing some thicknesses. i have a rubber torsion axel rated for 2000lb that gets placed centered on the two plates. I plan on half inch ply wood for the floor maybe eventually upgrade to tread plate. please give you opinion cuz im trying to go the least that i can but i dont want a weak trailer. thankyou

    Your new BOM is safer for all.

    As far as the floor is concerned, stick to the plywood. Wood has a better resistance to slipping, you know the stuff you put into the trailer won't walk about.
    Looks like you have enough support under the wood to keep the heavy stuff from falling though. Since you have a rating of 2000lbs I think it all looks good.

    Enjoy your trailer.

    thats trailer tongue need to be plated or ribbed to reinforce it ive used raw aluminum trailers for highway before it either needs to t6 or have 1/4 to 3/8 plates to resist bending and stretching

    also for the weight s would want it might be better to go how you fame floors with 2x4 vertical to hold stronger but make it out of 2x4 aluminum box tube

    other than that itll be a great little trailer make a mini headache rack for 2x4s or pipe that longer than the trailer
