Thaks for asking, i should have typed it within the original post.
Unlaiden is around 2k lbs, can handle 4k more as best i can recall. Upon looking up on the internet, am copying/modding a bit the below from a website:
Thule Cargo Pro Series 3000 Aluminum Trailer
7 x 18 Enclosed Trailer With V-Nose (so you really get about 19.5 feet of 'box' and the remainder is the front top and bottom cabinets.
GVWR: 6000
Empty Weight: 2000
Load Capacity: 4000
Rear Door: Ramp/Drive On
Side Door: Yes
Axle: Duel, both have brakes
Color: Silver (keeps heat way down in the summer months imho and why i chose that color)
Accessories: V-nose trailer, 120 Volt wiring, v-nose top and bottom cabinets plus LOTS of e-track and PitPal goodies. Those who have seen it at COMSCC or SCCA events know i usually buy the very best and keep it that way. Ad to that, aluminum trailers tend not to rust, do not need repaitning like other metal types, and are MUCH lighter. The v-nose is very aerodynamic, too, versus the air brick of others. The series 3000 has alum 5-star tire rims, includes new full size spare tire had LED lighting, rear loading lights, internal 12V and 120V box lights...
Aluminum trailers also hold their value quite well.
