Howdy! We just bought our NVP 3500 SL last Saturday after three years of drooling. We LOVE it. We have five kids and also want to RV. I think you will be happy with whatever you go with as far as RV - but we are looking at something hybrid and under 6000 lbs. I'm a newby at towing and don't want something too big. It's up to your comfort zone. As far as the NVP - go for it. You won't be disappointed!
