Here's the deal. I have a 15,000 lb 5th wheel camper, a wife and 5 kids. I own a 2009 F350 that I drive everywhere just so I can pull a 5th wheel on camping trips about 6-7 times a year. Would it be possible to take an M35 or something similar, and add a 5th wheel hitch as well as an extended, enclosed (safe) cab that will hold my whole crew (me, the wife and a kid in the front seat and 4 more kids behind)? Is the bed long enough to tow a fifth wheel and have an additional cab (I would think the additional cab would need to be about 4 feet and I would just put in a 4 seater bench)? Is the bed of the M35 or like vehicle too high to pull a 5th wheel camper? I have a budget of about $12,000 but I would love to get it done for under $10K. If I could pull this off I could sell the f350 and get a more reasonable commuter car and then have the M35 around to pull the 5th wheel. I am excited to know what you all think!
