Grand Design 337rls reflection

Hi, We just purchased two of the 337Rls models this week. If you need any info just ask, we have been over them with a fine tooth comb. My wife and I drive a 2011 Ford F350 4x4 SRW, our friends who bought the other unit drive a 2007 Chevy 2500 HD 4x4, On the trip back home we noted that due to the pin weight 2080lbs there was a little sag in the Chevy 2500 HD, the F350 had no issue. The driver of the Chevy will have air bags installed. Both of us are very satisfied with the units and both trucks will pull them, however the 2500 will be maxed out on pin weight. If you have not ordered the truck, I would suggest the 3500 for the additional weight capability at the pin location. The cost between the 2500 and 3500 is minimal. They both ride fine. The 337Rls has the axles a little farther aft which allows for better tracking but adds some pin weight ( the 303 model has a pin weight of about 400lbs less due to axle location a slightly less trailer weight). You will enjoy the model. good luck
