I have narrowed down my search for a new TV. I am going to order a 2011 Chevy 3500HD, Crew Cab, Long Bed, 4X4, w/ the LTZ package. My final decision is SRW or DRW. I would like some opinions based on the following: -I will be towing a Montana 5th wheel (2955R)L, which will be fully loaded with a GVWR of 13,725#. -We will be FT RVing, through out the states, Canada and Alaska -I will be using the TV for some daily driving in NJ during November and December each year. -When towing, it will be myself, DW and our dog -I will be carrying 2 kayaks, a 250# gas scooter and 2 bikes on the TV -The 2011 Chevy 3500 SRW has a GVWR of 11,000#, GCWR of 24,500#, a 5th wheel trailering rating of 16,800#, and a maximum payload of 4,268# -The 2011 Chevy 3500 DRW has a GVWR of 13,000#, GCWR of 29,200#, a 5th wheel trailering rating of 21,100#, and a maximum payload of 5,905# -The SRW TV has Hill Assist Start, Stabilitrak Electronic Stability Control (senses loss of lateral traction, understeer, and oversteer, and automatically adjusts brakes and engine torque), Trailer Sway Control (works with StabiliTrak, and senses trailer sway and automatically applies TV brakes and reduces engine power as necessary), and Automatic Locking Rear Differential. THE DRW HAS NONE OF THESE AND RELIES ON THE DUAL WHEELS FOR CONTROL. -Identically equipped DWR TV cost ~$250 less that SRW. My questions are: -Should I go with the SRW or DWR? -When in the snow and not towing, is the SRW with the above listed stability/sway/traction controls, better than the DRW? -What sort of MPG reduction is normal with DRW (towing and non-towing)? -Is there anything else I'm not considering? I have talked to a number of dealers, but they are clueless. Ideally I would like to go with the SRW, (better MPG, less tire cost, easier to drive when not towing, BUT I DON'T WANT TO MAKE A MISTAKE AND UNDER BUY. All advise appreciated and welcome.
