2013 Dodge 3500 DRW Gear Ratios

Hello everyone.

The wife and I just purchased our first 5th wheel a few weeks back. It's a 2012 Forest River Sierra 345RET. It weights about 11,000lb dry. For a tow vehicle I'm looking at a 2013 Dodge 3500 Mega Cab DRW.

My question has to do with gear ratios. Should I go with the 3.73 or 4.10? The majority of our towing will be done on Highways across Eastern Canada and I will also be using this as an everyday vehicle when not pulling the 5th. We are going out west this year for the honeymoon but that's just one trip in the mountains. I'm leaning towards the 3.73 but thought I would ask around first. I don't see us going any bigger than this trailer we have now.

Thanks in advance.

  • That would be my choice based on the possibility of future larger trailer. The 3.73 are good to 24K trailer. 4:10 take you to 29K+

  • Having had three Rams with the 3.73 it will do well unless at a later time you might want to go to a larger/heavier coach. JMHO
