5th Airborne Pin Box

Thinking about putting a 5th Airborne on my Crusader to smooth out my ride. Has anyone done this or thought about it? What do you factory guys think?

I can't say that we have any experience installing a 5th Airborne so your best feedback would come from the dealer. Sorry.

My Dad sure does like his. He's had his for 5 years of towing his 5th wheel and he loves it. I've never used one, but would like something to help in the concrete jungle towing experience. Someday.

Or better to say " your best feedback will probably come from members of the forum"

By smoothing out your ride do you mean the back and forth "chucking" the trailer gives on rougher ( especially concrete ) roads? Or is it the up and down seesaw motion like you get when you go over a dip or hump in the pavement?

The seesaw motion is not typically continuous where the chucking can be. I had a Montana that I simply could not stand to tow very far because of chucking. I bought and installed a MorRyde pin box and the difference in towing was dramatic. Well worth the money. I cannot say if the Fifth Airborne unit will control the chucking as well, word is they work good on the seesaw motion, not so much the chucking unless you buy the high dollar unit that has a similar rubber cushion like the MorRyde.

I installed one on a 32 ft fifth wheel with 2000lb pin weight on a 3/4 ton truck. I liked that the shock and air bag were hidden. However,once installed, I didn't think it helped at all.

I've read lots of positive reviews on both the Mor/ryde and Trailair Rotoflex pin boxes. I was asking the factory reps on another thread for their input on including these type of pin boxes as options.

I have experienced 'chucking' on our set-up since I switched tow vehicles to a 3/4 ton. I going to try to increase the pin weight by 300 lbs by loading the camper differently. I believe that the pin weight is too low for the heavier suspension of the F250.

I've had similar results as Dave. I used to only carry a small amount if water in my fw tank. Lately I've been filling the tank. The ride has drastically improved and haven't noticed any real change to fuel economy.

Dave, pin weight ( or tongue weight on bumper pulls ) can have a big effect on how well a trailer tows. Well worth the time to see if the results are good, as long as you stay within the ranges recommended by the manufacturer. I tried towing with full water tanks, empty water tanks, etc. but found the chucking was always there. Chucking is caused by the trailers axles/tires pulling against the truck as they meet resistances in the road. This can be a slight rise in pavement, uneven blocks of pavement, potholes, etc. The trailer can also try to accelerate the truck when "going down the other side" of these obstacles. In other words, any time the trailers tires are going a different speed than the trucks there will be a tug or push against the truck. Doesn't take much of a difference to feel, and since the trailer weighs sometimes twice or more what the truck weighs, guess which one gets moved back and forth? This is chucking. Some trailer suspensions can absorb these changes in the road better than others. My Sanibel has shocks on all four axles. I am convinced these are a huge aid in suppressing chucking. The MorRyde and designs similar work to absorb these momentary changes in speed difference between truck/trailer.
