Haulmark trailers ok?

The haulmarks are a good trailer, but as everyone mentioned, get the heavy axles with torsion flex. Trailers with leaves bounce too much and kill the shocks on your race car. If you travel a long ways with one, put your hand near the shock and feel the heat!! Do not touch it!! Also, my trailer is a 24 ft interstate and it weighs 5000 empty so that only leaves me with 5000 payload. Imagine if you only had the 3500 lb axles! I don't know how much it matters but that one listed has the floor crossmembers 24 inch on center whereas mine are about 12-16 inch apart. Makes for a stronger tie point for the floor d-rings. Flat one piece roof is nice though. Less areas to leak.
