Original Post-
Bought a couple hundred dollars of metal earlier this week after spending months drooling over this site then scouring the internet for a prebuilt, lightweight, torsion axle, braked 5x10 trailer (to no avail.) The metal was delivered today and I didn't waste any time gluing it together! I've got a 2x2x0.125 rectangle and a coupler with 2 six foot sticks of 2x3x0.125 stuck to it sitting in my garage. Tomorrow morning I'll put 'em together.

My inspiration for this build is the LG Silver Shadow sitting on the lot at my local RV dealer staring at me, a beautiful trailer but a bit to precious for my wallet! Besides, I needed a project. I think I'll skip the sink and built in stove, but I will add a 5000 BTU window rattler concealed inside the trailer in the rear overhead shelf (plans subject to change.) My goal for this trailer is LIGHTWEIGHT! I'm off to a bad start with a 5x10 instead of a 5x8 and a mandatory A/C, but I'll do my best to cross the finish line under 1000 lb. Wish me luck.

My plan is to skip cabinet doors with the possible exception of the lower galley door, in favor of shelves and cargo nets. I plan to build my walls from 1" HD foam with 1/8" ply skins. I'll weigh it up when I'm getting close to skinning, but I hope I have enough wiggle room to skin the thing in 0.040 mill finish aluminum. Paint doesn't appeal to me as it won't be store inside. We'll see (price may be a factor on this too... no idea how much it will run me.)
I have a 1 1/4 receiver tube on it's way from amazon, and before I fall asleep I hope to find and order 2 leveling jacks. Next on the list is an axle! Now's the big question... Dexter or Flexride? My current TV is a Golf TDI, which is pretty low to the ground. However, I see a new car in my relatively near future. Because of this, the adjustability of a Flexride appeals to me... how big of a deal will it be to find the appropriate rise/drop ball mount to make the trailer sit level if I get a small SUV for example? Another thing that concerns me is the sag of the Dexter over time... not sure if this is an issue or not. The biggest factor will most likely be price, I plan to find a local dealer or two and get a quote early next week for the Dexter. I think my wallet will be the deciding vote.
Anyway, I've started! I can't say whether or not it's a good start but I've got metal dust flyin' and the wife's support! (with 1 condition... the trailer gets A/C!
