Is this Ford F450 XL durable?
That's kind of a loaded question-I know several people that could destroy it in no time, some people could ruin a anvil. As far as major problems probably no more than any other rig of that size.
Depends what you define as durable - personal opinion as the owner of 2 aluminum body Fords - I wont own another one. Bodywork is $$$ because of the aluminum. Also very few shops are actually comfortable working on the aluminum. One truck was backed into, while parked. Minor damage really, but it ended up getting a box side, cab corner, and door skin. All for what in a steel body would have been really minor work. Had nearly identical damage on the other side of the truck when a staff member cut a corner too tight and clipped a skidsteer bucket. Only door skin and cab corner on that one...way too expensive. Mechanically though, the 6.7 is well proven, and seems solid. A buddy of mine runs one in a tow truck application and has over 500,000 miles on it, without opening up the engine. Last I spoke to him, all he's done is a rear end, and 1 injector - which he though was from bad fuel.
Which F450? We talking late 90's or new? Gas or diesel? Standard or Auto? Etc.
