Yes you do. The only bumpers that don’t require cutting to my knowledge are Slee, Dobinsons, coastal off-road and Jason at trail tailor was doing one at one time.
I have put our Higgy’s bumper through its paces off road and has held up and stayed as quiet as when I installed it on my rig a year and a half ago. That is a 37” tire also without any issues. Our sale is running till tomorrow at midnight. Discount code BLACKFRIDAY gives you 15% off. Higgys.com is where you can find it. In stock ready to go
I welded an extension onto the jerry can holder and created my own hi-lift mount. It worked well but I had to replace the jerry can upper ring and never got around to putting the hi-lift mount back. I would do it the exact same way.
