Swinger Rocker/Quarter Drain Question

Ok, got the inside taken out of the back, pulled some floor plugs and used a shop vac and then a hose. It's like a different car now. So much dirt and dust back there. There was a couple inches of dirt inside the quarters.

After vacuuming what I could, I put the garden hose inside there and cleared the drain slots underneath....kept at it a while and now it's all clear and clean.

Thanks for all the help!
