Tow vehicles - Event Date: 28 Sep 2017

Great video! Thanks for sharing it and its one that I think anyone pulling a trailer should view. I completely agree with the video and your conclusion. If you’re ONLY using an airbag system or a product such as SumoSprings to compensate for trailer weight distribution you will not get the benefits that a good weight distribution hitch (WDH) gives you when towing. Even if you have an additional suspension system improvement such as the airbag or SumoSprings it should not take the place of a WDH so we are in agreement. I too use the Fastway e2 WDH system that also gives me additional anti-sway control which I believe is very important. Any aftermarket shocks, airbag, helper springs, or a product such as SumoSprings should only be used as an additional improvement to your vehicle suspension system and again not as a replacement for the WDH. I think we’ve may have gotten our apples and oranges mixed up on this subject, if so forgive me.

I will have to respectfully disagree with your conclusion in that there is a difference between SumoSprings and airbag suspension systems. SumoSprings are a “passive” system where air bags are “active” suspension system. In all airbags you have compressed air inside which uses some type of bladder system. They work great as long as they are always maintained, correct pressure and such, and never have a puncture. Where as SumoSprings are made out of a type of foam which requires no maintenance and no worries about leaking from punctures. Unlike airbags SumoSprings, which replace your leaf springs rubber bump stops, only exert full compression under heavy load. The SumoSprings are used to help stabilize and support your load which can only help not hinder when using a WDH. In no way have I found them negatively effecting the suspension stabilization but only improving it which is what your after by also using a WDH. If you believe something like SumoSprings or airbag suspension systems don’t work when you use a WDH. Then I suggest that after you do a long haul with your camper reach under your rear wheel fender opening and grab your shock and I’ll bet you’ll find it quite warm to say the least. Its why many people upgrade their shocks or suspension systems using products like SumoSprings or airbags with or without WDH when they are pulling a trailer or hauling heavy loads. If you still don’t think either suspension systems work then I ask you why do you think tractor trailer trucks use airbag systems? If that doesn’t convince you well to each their own more power to you brother.
