Advice! What's the best company out of...

Melton is an irregular route flatbed carrier and can stay on the road as long as you want.
Irregular route means they run all 48 states and go where ever the load needs to go. I did irregular route with flatbeds and reefers and prefer that to having dedicated boring runs that are the same day after day.
Someone posted a couple months ago he saw Melton trucks in Alaska. First I've heard of that.

Paul Transportation flatbed hauls lots of oil field supplies to oil fields across the nation.

 

The websites have "short apps" you can submit from your home computer. Trucking companies will look those over and contact you. You'll have lots of job offers. It's a great career; it is for me for sure.

 

Get Hazmat endorsement now.
Solo drivers pull hazmat loads which may be as simple as cans of spray paint or fingernail polish. Pulling reefers, that hazmat endorsement keep me rolling because when a refrigerated load wasn't available, I got a hazmat load. One time, for example, in Ohio I unloaded and called in for my next load. Only thing available was cans of spray paint going to Los Angeles, California. I was on my way and didn't have to sit in a truck stop until the next day waiting for a refrigerated load.

 

Used the reefer trailer with the unit turned off; perfectly legal.
Another time hauled a load of tires from Tennessee to Phoenix, AZ in a reefer trailer.
I really like irregular route trucking. Never know what's next. An example when I pulled flatbed; load of lumber from California to Northeast. Reloaded with spools of electrical cable going to Seattle, WA. Had some room left on back of trailer, so dispatcher diverted me to another place to load a boiler headed to a school in Burnaby, Canada. Got those two stops off and was sent to Ft. Lewis, Washington to load an Army truck headed to Wilmington, North Carolina.
Never ends, just on and on when I pulled reefers and flatbeds.

 

The orange one!
