We are nearly ready to ship our Jeep to Africa. We got our Carnet through ATA Carnets and noticed that I underestimated the weight of our vehicle when I got our Carnet. Now we have the Carnet and it reads about 3000 lbs. lighter than the actual weight of the vehicle. I didn't weigh the vehicle until after I ordered the Carnet, I just estimated its weight. Will this be a problem in Africa? Should I contact ATA (boomerang) Carnets to have it corrected?
