Does anyone tow an SRX behind their RV? I plan to tow with a dolly, and the owner's manual for the SRX says this can be done with the rear wheels up. The dolly company, Roadmaster, says it can't be done. I have seen one SRX being towed 4-wheels down. I know a driveshaft disconnect is needed for that. Anyone with any experience in this? I have a 2007 SRX.
