Short answer is yes, but you will be close if not slightly over depending on how you load it. Engine is the same SRW or Dually. Not sure on the build ups available in Ford for SRW and DRW on the tranny or rear ratios which is where you are going to find the differences. Ram has many variables so not all are equal.
If you are going to be hauling for a year I would vote for a Dually for the the added support and stability. If you own the truck already, then you could get by like many others do and be happy.
