All my trucks have air bags... and the B & W turnover goose neck hitch in the truck... We see3500-4500 lbs hitch weight if the trailer is loaded wrong... . I know that my 5th well trailer has no where near that weight..... We use the B&W Companion hitch... Now that I think of it, it might be B&D... . turnover..... Oh well. . you get the picture... . the trailer can go up to 24,000 lbs...
