Do the airbags
Hi to all. First time posting here, but very active on the Redwood forums.
This is a discussion we've had many times.
FWIW - my rig is a 2013 Redwood 36RL pulled by a 2013 F350 Dually. Total GCWR is 27780 and the coach alone is 16,600 . My RW is pin heavy and I'm running about 3540 on the pin. All weights are within specs and when the truck is hooked up I sit level.
I've added Airlift 5000 bags with the onboard compressor and remote and also added the Sulastic rubber cushioned rear spring hangars. I had Helwig sway bars on the last truck (F350 SRW) and am considering adding them to the Dually . Also have Bilstein shocks.
The hitch is a Comfort Ride Cushioned suspension hitch and the Pinbox is MORRyde. Coach also has MORryde IS Suspension system and Kodiak disc brakes.
The airbags were added for suspension control. If you look at the suspension when loaded, there is only about 2-2.5" of clearance from the axle to the suspension snubber above it that is made of hard polyurethane. By adding the airbags, I replace that hard snubber with a device that I now have total control over. I've also almost doubled the distance of suspension travel before it hits the snubber.
With the combination above, my ride unloaded and with about 5lbs in the bags is actually better than my previous 150. Loaded and with the coach behind, Ride is very smooth, virtually chuck free no matter the road ( has to be a REALLY bad bridge joint or dip to feel any) and well controlled.
Braking is every bit as good as the truck alone. The big discs on the trailer just haul it right down.
And if anyone is curious, yes, we tow quite a bit. Th rig isn't 4 years old yet and the coach has been towed in excess of 28k miles.
Short answer. - Definitely do the bags
