>>>>Am I correct in assuming the only reason they put the sub 3k limit on most single axle trailers is because the manufacturers don't want to put the brakes on? I thought the 3k brake rule didn't apply EVERYWHERE anyways.
I'm not sure of what each particular states laws are regarding brakes, but across most similar forums, the consensus seems to be that everything under 3000lb gross is exempt from brakes.
Manufacturers likely use a 3500lb rated axle on a 6 x 12 for example, because if they didn't, once the shell is on, people would be very limited to what they could actually carry. That is why another lesson in single axle trailer selection is to watch the trailers empty curb weight. We find some manufacturers claiming as little as 950lb curb weight on an aluminum frame, whereas mine claimed somewhere around 1200lbs. While the 950lb trailer might have the exact 2990 rating, One can be assured that there simply is not as much material used in the construction itself.... like floor or wall members on 24" instead of 16", or using "Z" shaped flimsy channel compared to tubing.
Purchasing a 7 x 12 or 6 x 14 single axle carries similar concerns as the structure weight obviously climbs, but the 2990 limit is still in place, which cuts into the actual load you can haul. Back to the 950 Curb weight, one has to wonder just how a 950lb aluminum rig might hold up at a 3500lb load simply because brakes were added, but with less materials used in the structural build.
Mostly however, I think the manufacturers realize the $$$ Value of NOT putting brakes on this size trailer. First, the laws are written as such which helps, they can focus on large quantity purchases of ONE axle, a 3500, then de-rate things under 3000 on the tags, but best of all, tag on a rather incredible cost increase for adding brakes for those who do not know just how inexpensive and easy a brake kit bolts onto any modern axle with the flanges already welded in place.
In my state, NO ONE is suspect of whether brakes exist or are required or not by law for non-commercial looking vehicles. DOT vehicles will pull over business entities for quick checks, but fully ignore even the most ratty looking trailer even when obviously overloaded. Likely, things turn more serious if an overloaded, non- braked trailer got into a crash, and insurance and lawsuits took place. At least I no longer see WOODEN tongue poles anymore.. at least not since cheap welders started showing up in most garages.
I'm mostly concerned about how a DOT or State Patrol Officer would react to the 2990lb tags, being weighed at say, 3300lbs, and me pointing and saying "but LOOK ! I added Brakes! ". I'd like to think if the rig is clean and well maintained, nothing would come of it.
