hey all, quick question- I got a 7x16 car hauler heavily loaded for a car show this weekend. Need a WDH but not sure which one to get. The 800 lb costs the same as the 1000 lb, should I just get the 1000 lb? Is overkill good when it comes to WDH's, or will it cause problems by unloading the rear too much, and wearing my front tires? I'm coming back with just a car, so how quickly can they be adjusted (to compensate for the lighter load), or is it a big time consuming pain? Truck sags about 3 inches with trailer on it, so I know I need something! thanks!
