Never had a trailer for work, but have had a couple of camping trailers. My first one was a Coleman pop up, no brakes. It only weighed about 1,000 lbs and I had no problem stoping it with a GMC Blazer.... Now my 25' travel trailer was another story. Got a suburban, weight distribuiting hitch, brake controler etc...Say whaaaaa??? I thought ALL enclosed came with brakes on the axles? I've never gave anything under 20' a second glance, but just assumed for safety sake they had'em? If no, that's ridiculous.
