Looks nice so far, but a lot of work yet to make it road ready. If it's intended for use only in field or off road disregard the rest of this post. Seems like a lot of fuss, but that is one reason factory built stuff costs more than a pile of iron & a box of welding rods. Take a close look at factory built trailers. They are built to minimum legal standards. Some may call me picky, but get stopped on road or involved in an accident & it will get really expensive. Even if other vehicle is at fault, you don't move from the scene until defects are corrected or the whole thing is loaded on a legal flatbed. Don't scoff. Couple years ago I had to rescue neighbor with a load of firewood logs. He was pulling a borrowed home made trailer, lost a wheel. DOT car got there first. Got tickets for over truck weight rating, over hitch rating, bent hitch, illegal tires ( marked mobil home only) no brakes, 16 lights missing. Called for tow service with roll-back truck. Load too heavy, had to call construction company with lowboy trailer. Hard to find a driver on a summer Saturday afternoon. Total cost of fines & hauling well over $1,000. He now has stronger truck & factory built heavy duty trailer.
1- BRAKES!!!!!!!!!!!!!!!!! Looks to be capable of over 3000# loaded weight. Some states allow to tap truck hydraulic system IF wheel cylinders less than a certain size. Otherwise need electric over hyd system or replace axle with electric brakes. Most states also require breakaway control able to stop trailer & hold 15 minutes if it comes unhitched.
2- remove the red parts of the reflective tape from front of fenders. Red is not allowed visible toward the front.
3- lights: Red showing to rear & on side within 6 in of rear. Rear turn signals may be amber if seperate from tail & brake lights. All other lights amber. The red side lens on the lights in pic is not legal, too far from rear, must be amber.
Looks to be over 80 in wide. Clearance/markers front & rear at widest point (fender corners) Must be seperate from regular tail/turn/brake lights.
Corner markers- sides, & front & rear corners of box.
ID (3 cluster/bar) front & rear, mounted as high as possible. If tailgate is removeable, rear bar may be mounted at bottom. Front not required if truck has 3 cluster & cab corner markers.
4- mud flaps or body panels. Ground clearance not more than 1/5 of distance from center of axle. EG: if flap is 30 in from axle, ground clearance not more than 6 in, if 50 in from axle, may have 10 in clearance.
5- safety chain hooks, strong enough to control trailer if it comes unhitched. Must have keepers to prevent hooks from accidently unhooking. On gooseneck chains must contain coupler within truck bed. On bumper pull chains must prevent hitch from touching ground.
End of rant.
