My camper is narrower than the standard. I think mine is 7' 9", where as most, such as Northern Lite, AF, etc. are 8ft? That is why I showed the extended width from the camper sidewall.
We have a 2014 Ram dually and we have about 1" clearance between jack legs and rear fender. So, I'd assume that a wider camper would give you more clearance?
