That first early oil change is very important I always check the oil filters and you'll find there'll be more metal debris etc. In that filter on the early oil change than you will on the regular oil changes later on in the cars life.
I did my first oil change at 1000 mi oil on dip stick was at top of hash marks. Drained oil from pan stock plug seems fine and lets all the oil out then removed oil filter very easy let it drip for about 15 min then pulled the pan out to dump into recycle tank and put clean pan under the oil pan...
Are the stock Beadlock capable rings capable of being a true bead lock or do you have to purchase new rings to have true Beadlock wheels like my F150 Raptor.
