Andy: i agree absolutely, my choice of two is based on using a particular trusted supplier, these are their core brands, so their engineers are well versed in the technology.

John: You have been in the business 401 years? wow! i take your points though, we are replacing trucks that are coming to the end of a 5yr contract, i may have been a little optimistic on hours, but i think our highest usage truck has about 14000 on the meter. after 5.5yrs.. I have been severely stung for excess hours on these trucks, so will be asking the new supplier to review hours annually and adjust contracts as necessary as we go through the contract.
