So as someone that owns a Bronco, too, although mine (my almost 16 yo son's actually) is not a Braptor, I highly doubt you'll miss it much after driving the RHO for a few days. The HP difference alone will make you smile from ear to ear. I actually came from a 2024 Sierra 1500 AT4X with the 6.2L (420hp) and the RHO is night and day better! With the Braptor putting out similar performance numbers I'm willing to bet you really won't miss it, aside from the ability to remove the top and doors that is.
As everyone else has said, Level 1 is pretty much a no brainer because there's so much to it. And I'm sure the Braptor is pretty well outfitted so leaving the Level 1 package out I think you'd feel like you're missing something. If you're looking to tow with it, probably add the towing package and maybe tow mirrors, too. I originally was thinking the mirrors would be too big and look stupid, but honestly with the RHO being a wide body, they fit perfectly! The bed utility kit I think you can probably leave out and just get the bed lined. But it is nice having the step to climb up as the RHO is a bit tall for my short-legged ass! Beadlock capable wheels are very nice....but definitely not a necessity as there as much better aftermarket options out there, especially if you want real beadlocks. The Beadlock ring kit for the factory beadock wheels will run you about $1200-$1300 and then you have to have them installed so at that point you're $2500-$2600 into beadlock wheels....that opens up too many other aftermarket options IMO. Offroad sidesteps or sliders....again....a few aftermarket options out there that others are installing so that's really a personal preference thing. Granted I have all of these options but I just happened to find mine sitting on a dealer lot waiting to be plucked and given a home. Myself, I can't imagine NOT having all of the options I have but I'm sure I could live without a couple of them. The rails that come as part of the bed utility group I'm not certain I'll use but since I have them I can probably find a use for them. I've actually considered pulling them out and selling them here locally, which is still on the table.
All in all, if you can find one optioned the way you want for the price you're comfortable paying....go for it! You won't be sorry regardless!
