Delivering RVs as a contract driver, WA resident...

I run with a SMALL company (12 ish drivers). We hired one guy without a 5th wheel hitch and they were able to keep him loaded for about 4 months with bumper pulls. One trip he headed to Elkart to pick up and discovered the trailer was a 5er not a bumper pull. He had to sit for 2 days until another unit was found for him.
I would say you probably can get hired on but you will be limiting yourself. I think I have only seen this one truck without a hitch in the year I've been doing this.
