Waste Management vs Republic Services

[Reid Hanley]

I'm researching costs for providing a trash dumpster to a Mobile Home Park I have under contract.  The current owner is using WM and their current monthly contract rate is $525.  Over $6K per year for trash pick up seems exorbitant to me.  Republic Services website has the same size dumpster priced at $165 per month.  Is there a big difference in service quality between these two providers?  Just can't get my head around why WM is so expensive. 

Any insights from you MHP owners that have used either or both providers?

Thanks BP!
