For sure could be done and I considered it when I first got mine as the factory intake is sooo in a dust receiving area. Underhood I was concerned about dust potential, water ingestion from puddles, deep water crossings and opted for 1/2 way up the rear of my cab. Have pix in my link for what I did. In addition I wanted to leave room for underhood storage, e steering and auxiliary battery etc. Plus 1/2 way up cab seemed easier to do.
Cheers,
