Fishstu, I pull My 20 MA which is Heavier than Normal with a 97' Jimmy 4.3 V6- lock diff. 3:42 gears. Nothing else added except for Fac.towing as You have. The P/U 's are lighter in the rear which may make You Adjust the Tounge weight if You slip at the Ramp.Trick; 2nd Gear barley give it gas just to start rolling. Apply slight emergency brake pressure if its slippery,as long as the rear wheels don't slip she'll come out slow. The Tandem axle trailer will pull much easier. DO NOT USE Electric brakes,Problems will start happening. Surge brakes are all You need & on one set of wheels. If You have a Complete S.S. Brake setup(As Rolls Axles) You do not need to flush,Although I do spray them. Air shocks;You will just have to see how it looks & tows to determine if You need to add air shocks,again the tandem helps greatly with the load.The electric brake contoller is Great for campers,horse - utility trailers etc. They can be adjusted to stop the load as Your putting the truck brakes on. Surge Brakes;You will have to Run an extra wire from Your Reverse light(Usually lt. green or lt. blue) to the trailer.This will allow You to back up.Otherwise the weight/surge will cause the brakes to come on .You can buy a 5 wire harness or just add a slip connector.
