Sumo Springs on my Toy Hauler
I bit the bullet and spend $500 on four small rubber type things to augment the suspension on my Forest River RR19 toy hauler. Check out my you tube video here...https://youtu.be/xSDd5Se4z2E

Two hundred mile trip yesterday ....and in a word..."FANTASTIC". Hard to believe how four urethane cylinders could improve the ride of the Tow Vehicle. No more jerky jerky when going over bridge expansions. No more bucking on washboard roads. This trailer is a toy hauler. Designer to carry a 1000 pound toy. When unloaded the suspension is very stiff. These Sumo springs smooth the suspension right out. I bought them from Amazon so I could return them if they did not work as advertised. But I'm starting to believe they might be the best $500 I've spent bon the trailer.
All the internet engineers on this thread might be disappointed that they actually work. Sorry about that.
As far as the post about them not contracting the chassis. Watch the video again. That picture was with the chassis jacked up and the whole spring system hanging. When you install them. You add spacers to maintain about 1/2" of compression.
And as far as the comment about the Sumo springs bending or otherwise damaging the frame rails..... Totally ridiculous..... And I AM an engineer!:)
