Hi all. Just registered to this forum; or any forum. My background is in the natural gas transportation industry. The wife and I are empty nesters, to a degree, and are contemplating retirement. Want to get an RV, but first need something strong enough to pull it; hence the interest in Ram trucks. Have been looking on computer for a while and many questions have come to mind. My 1st question is what is the difference between "trailering package" and "trailing prepred"? Have seen this in many used truck aids. Next question: Is there any significant cost difference in installing a 5th wheel hitch in a Ram verses Ford or Chevy? I was told at a very large r.v dealership in Louisiana that to install the 5th wheel hitch on a Ram truck was 2-3 times as costly. Did some research but haven't found any information concerning this. Will appreciate any input.
