My wife and I just sold our chinook 21' and want to move way up to 32' 5th Wheel, either an Artic Fox or Montana by Keystone. These show weights of 13,000lbs, but I don't know if this is empty or with the full capacity. Anyway, we are therefore looking to purchase the right tow vehicle. I am looking at two, the Ford 250 or 350 and the Dodge Ram 2500 or 3500 single wheel with the 6' bed (I think that is medium). Any recommendations or suggestions would be appreciated. Also, where I can get accurate information about towing weights would be helpful. Thanks to everyone in advance.
