I tow with a Dodge 2500 with an added leaf spring ( $500) makes the Dodge 2500 the same as 3500 SWR. With the spring, unit is 100% level and drops 1 inch when hitched. The built in exhaust brake ensures that on a 5% downgrade, I often need to ACCELERATE. Hardly ever need the brakes! The front patch tire contact is EXCELLENT. I run Michelin tires on the truck. Towed my 2015 6,000 miles so far and never even the slightest wave from wind, rain, hail.
The newer trucks ( mine is 2008) have even more improved stock suspension from the factory. Our RV does NOT HAVE a washer/dryer in master bedroom AND more important, I have the factory installed optional TrailAir hitch with air adjustable suspension. No chucking or jerking of any kind. Nothing in the RV shifts, nothing.
Every person has to do what they feel is right to make their experience safe. Do the research on YOUR VEHICLE OR CHOICE OF UPGRADE and go with your choice.
Our last fifth wheel was a 2011 Keystone, 36 ft triple slide. Towed it with this same truck 7,000 miles from east coast to Arizona and all parts in between like mountains in northern AZ, Grand Canyon, Route 66, thru ice in Amarillo, TX, dust storms with 50mph crosswinds. Never a problem. Had several hazardous prevention braking maneuvers. Not one minute of blood pressure rise or white knuckle concern.
Make DAMN SURE you buy a tire pressure monitoring system. I had a blowout on FL turnpike south of Disney at 65mph AND NEVER FELT IT! A bus pulled along side and alerted me. Cost: $3200 damage.
Have fun. Be safe!!
