Official capacity is 200 lbs, however, I have several friends that weigh over 350 and ride without an issue.
And, riding on the back of another person's CT to get back to retrieve the truck when their CT fails for some reason happens every now and then (rider and passenger over 350 lbs).
There are probably many other examples out there of carrying more weight than the official capacity.
Do what you think is right for you.

Paved roads, just more needless government spending...
