Nice looking- and excellent welding
I saw your other post on trailer weight and yes your design looks heavy, but basicly indistructable
Mine completed dry has to be easily 800lbs or under
weight savings....I used aluminum panels rather than steel for the superstructure, with light wall 1 x 1 and 1 x 2
3.14lbs/ft sq for the steel floor ouch I used 1/2" ply at more than half the weight.
You have used the same size cross members as the frame sides
which is over kill, especially when you've used a 2mm steel floor.
I used 2 x 2 light guage to suport the floor and add some strength without too much weight, and just 2 and an extra 1x1 angle in the front.
my side rails are full length just notched bent and welded so their stronger than a welded front triangle and also did'nt require a full size cross member.
My side rails were 2 x 3's rather than 4" too, which yours look to be.
If you want to haul gravel or sand at the weekend then its perfect for a ton or too.
I think we all build diferently and for diferent expected load weights.
Mine was for extra space rather than 800lbs of hot dogs in brine and a wrought iron grill
mm just checked the photo's I used some 2X1 channel as well for the suspension mount cross members
and damm you have a clean garage...........
edit- just noted you intend to have to motos on the yoke.......yep you'll need it heavy duty to carry that weight
