Try this: mount the lens on your favorite mono-pod. Place the mono-pod over your shoulder and put one foot in front of the other. Advance. Slow, but simple and not too tiring and NO set-up required. This method has worked all over the country and helped me harvest years' worth of photographs. The best part might be very popular on this board, it is FREE!
And the last part. I recommend that you 'work up' to carrying this gear by challenging yourself. I knew I was going to Yosemite in 2019. I carried a 26 pound backpack for many months as I built up my stamina. - It worked! My longest day in Yosemite was about a 15 mile walk with this backpack and a handheld camera/lens.
