Toy Aluminum Boat Should I Put A Steel Or Aluminum Roll Bar For My 85 Toy Pickup, With Huge Mud Tires And 4-5inch Lift?

Should i put a Steel or Aluminum Roll bar for my 85 Toy Pickup, with huge mud tires and 4-5inch lift? - toy aluminum boat

I have a custom roll cage for my Toyota pickup 1985, the people say that you have an aluminum bar should be preserved, and spoke with some of my buddy that you should bring a bar of pure steel rolling like that when I flip, keep my car and almost my entire life. The roll cage is a habit, I'm back with a toolbox in a few hours behind them and as an aluminum bar and a custom steel roller, the weight would be for both, but I'm tires 35 or 38 inches or clay with a 4 or lift 5INCH it. Thanks
