I have a neighbor and friend who is going to live in a camper and travel the country. He will relocate 3-5 times a year and some things have happened so he's in a hurry. He bought this camper it's a 27 foot bumper pull he said it weighs 5800lbs. He wants to spend 15k tips on a truck. Could a half ton do this job or should he go bigger. All suggestions on trucks ect are appreciated.
