Hello out there I have a 2003 2500 HD long bed 4X4. I went to look at some slide in campers today at a show and I was told that my truck could only hold an 8 foot slide in. The sales man said that the dodge can't handle anything bigger. I find this hard to believe. I know that I can tow up to 12,500 . I've been told by others that I can go with a 10 foot camper and not have any trouble. The slide in camper I was looking at was the Artic Fox. Can anyone out there tell me what my truck can handle. Thanks BigMike.
