I am starting the build on our 18 GX and would like to get a front engine skid that I don't have to remove to change the oil. I was looking at the RCI cover but I found a few forum members that have said they had to remove the cover to change the oil. Who makes the engine skid that does not need to be removed to change the oil? Right now I have the following RCI items in the cart ready to buy. I have their sliders, transmission cover "aluminum", cat covers "aluminum" and was going to get the engine skid cover but I put that on hold. I have already installed our lift and tires with upper SPC control arms. Also should I grab the rear diff cover or wait on that? I will also be getting the extended range tank as well. Then the rear tire carrier/bumper and front bumper/winch. I have been a little slow getting this going but I am ready to finally get moving again.
