Surely You Want to Provide More Details About Your Trucking Experience by: The Crazy Trucker
If you're saying you don't need training and you want the chances of someone responding to your post, you probably would get further if you mentioned some of your experience.
You have to sell yourself. It's a big deal for people to trust you to drive their truck. Doesn't matter if you're paying or not.
They are more likely not to reach out if they have no idea who (experience, background in trucking, etc) they're dealing with.
Cause my assumption is based on how I am reading into your post is you might have just gotten training and didn't past the driving test.
But I'm guessing, due to lack on details.
And if that's the case, it's would make a person with a truck to rent feel more comfortable to reach out.
