Jcontracting- I would say we are a bit less than that and of those alot still don't go far. The good is once your in with commercial people you typically stay in unless you really mess up.
Landfakers- Thanks we mow with exmarks. Just switched to them this year.
Jbell- We have a undertailgate snowex new this season and a replacment tailgate snowex new last season. The under has been a disappointment. Both are not cheap and both have now come missing wiring and loose bolts.
The under tailgate auger came apart 2 weeks ago during a salting event, some pins on it have bent from normal use, some spinner problems and a few other things. I am not impressed and working on having the dealer buy it back and switch to something else.
To answer your question vs a vbox advantage is can haul more salt, Vbox also keeps salt off of the trucks better. Major disadvantage is liability of running the box up and hitting something cost is more for the vbox. Those are a few. With that said we may switch one to a vbox next season.
