Narrow body is your friend "off-road"
YMMV ... I've gone across many bridges in 96" wide body rigs with maybe an inch to spare. The good news is those old narrow bridges get less common as time progresses. However the passing of 2 rigs on a goat trail, is always an unpredictable challenge where inches often matter.
Tradeoffs, tradeoffs as we each have our uses and priorities to consider. If getting to a remote mountain top location matters, don't loose site of what can realistically make it there "and back" ... more than once
