We bought our EAZ-Lift WDH + Sway Bar combo for our Land Rover from a seller on eBay by the name of RV Adventures. They shipped very fast & everything was just as described. Also the price was very reasonable. Installation was very easy.
Here is a link to the seller I purchased from
Also I called EAZ-Lift manufacture because I didn't know much about WDH's. Their rep was very helpful this is what helped me make the decision to go with the EAZ-Lift Brand. I am still waiting for a call back from another well known manufacture mths later.
Most people say the TM doesn't need a sway control but I decided to just hook it up anyway for extra safety since we received one with our WDH.
Good Luck
