Since the build thread, I've replaced the coroplast roof skin with aluminum and skinned the back wall, as well as adding the rain gutter over the door. I also added a Ventline metal fanless roof vent.

I have over $1300 into the build, not to mention hours of labor, buckets of sweat, and volumes of cursing! I have almost $400 into the base trailer alone, including new (<1 year old, <500 mile) tires, LED taillights and wiring, and more.
I admit built quality isn't the fanciest, but it is a dry box for sleeping. It weighs <500 lb, and about 65 lb. tongue weight, so you can pull it with most anything

I think it's a fair price at $750 - NOW $650! you can't build it for that - but if you think it's not worth that much, feel free to make me an offer. Located in Las Vegas, NV.
