Have not done any maintenance on my 2004 Dodge ram except oil changes. What should I do first plugs?

The 4.7 in the Ram (at least for 2004 model year like I have also) calls for copper spark plugs only, that need to be replaced every 30,000 miles. It's easy and I did it myself in about 90 minutes. I have read mutiple threads that warn NOT to use anything else, as does the owners manual, no platinum, etc. I don't know why, my aunt's 2004 Jeep with the same engine DOES use platinum plugs. All eight copper plugs were $12 at the dealer. I only have 31,000 miles on my 2004 but every time it moves it is hauling something or pulling an enclosed trailer or a landscape trailer for a property company. I just changed both diffs, the transfer case, transmission, and coolant out for the first time, going by age over mileage. I would think these should be done every 40,000-60,000 miles, though the manual says the coolant can go 60 months or 100,000 miles I think. I change oil and filter every 5,000 miles or about once a year, and use Mobil 1 5w30.
