The RAM is an awesome truck, If you are going SRW be sure to get the 20 inch wheels. The 20 inch tires are capable of 3640 lbs and there is one that will go 3750 lbs. Though you might have a marginal load on the pin your tires will never be overloaded. They will support an axle load of 7280 or 7600 respectively. The 2015 2500 and the 3500 srw are very capable. But the 3500 comes with the upgraded aisin 6 speed transmission. The Cummins is reliable and the hp and torque is unbelievable. I had a problem with mine that was mostly dealer and self inflicted.
The quality of the truck is exceptional. 15,000 (15 Thousand) mile oil changes are easy on the pocket book. The EVIC center is unrivaled in the industry. I would not trade my 2500 SRW for love or money. The upshot is that the 3500 SRW Laramie with the transmission upgrade is very capable and nicely appointed. The GCVWR is well within the capability of the truck unless you are towing a freight train.The performance is beyond belief.
The DRW drivers will be all over me for telling you that the RAM 3500HD will Tow anything Heartland makes, and will support most everything heartland makes. The controllability of my 2500HD is excellent and I do not feel the need for a DRW truck. To me, my truck is a multi use vehicle and I don't want to haul around those extra tires and that wide wheel base when Im not using it to tow. Todays 3500 SRW RAM 3500HD has closed the gap and virtually eliminated the need for DRW truck in RVing. I will give credit and pay homage to the dually drivers, if you do buy a 3500hd in DRW you will have the king of TVs. But owning a DWR truck comes with some drawbacks.
I've been looking at the new 2015 Dodge Ram 2500 and 3500 and would like some owner's opinions on it's specifics; ie. tranny, rear suspension air bags, interior comfort etc. Also, what color do you have.
