new 3500 srw tow vehicle?

OK, it's time to look at Real World numbers. If that RL is like ours it arrived at the Dealers at 14000 Lbs without even a paper plate inside, no propane, empthy holding tanks and a set of D flashlight batteries (not really, but not much more). So unless you're towing an empty trailer those numbers are less than worthless. Gross is either 16K or 16.5K depending on tires and axles. So lets just go with the 16K, that will put your pin somewhere in the 3000 to 3500 Lb range, Because we have the on-board Genny and Combo Washer we're pushing 4K of pin. You've been living on the edge with a 2500 so if you go 3500 SRW you'll be a little farther back from the edge, but still too close for comfort. Go check the Redwood Forums, there are numerous members there who had 350/3500 SRW TVs they loved, but soon discovered they really needed the DRWs to handle the weight safely.
