My wife and I are considering an RV and want to use our Acura MDX to tow it. With a dealer modification, it can handle up to 4750 lbs and 475 lbs tongue load. I rarely see SUV's pulling RV's. I am looking for any thoughts / experience on how close to take the RV to the vehicle ratings and if using an SUV is the right thing to do. We have looked at some RV's that would meet our needs and they are in the range of 2800 to 3200 unloaded and 350 t0 450 tongue load. Will this work or should we consider another vehicle?
