Hi indept,
I think you chose the best spot to mount the remote filter base. I see you used the existing holes in the tow hook 'dog legs'. I will probably be doing a filter relocate in near future, and that was the spot I was eyeing.
I had hoped that I could use one of the Mopar 45 degree filter adapters (P/N 77072447 and similar) to make oil filter changes less of a hassle and protect my steering rack electricals. But starting about 2015 (?? judged from online 'does not fit' messages), RAM added a spin-on oil cooler (4893309AA) that's plumbed to my 2018 Laramie water pump and lower rad hose. It blocks fitment of the angled adapter.
Did you consider 90 degree hose ends to get the oil filter vertical ? I know they work sideways too, but I prefer to prefill the filter if I can. Which adapters did you use for the engine and the remote filter base ? I'm looking at some Hamburger's billet parts, but they're rather pricey, and I would prefer a remote base that has the hose connections at the top as yours does. Please share.
