Tandem Dump and tag trailer to move a dozer???

I'm looking for advice on moving my equipment before I buy the wrong thing. I have an IH TD-15C dozer that weighs in at 33,000 lbs. I'd like to have a tandem axle dump truck to haul gravel etc, something like a W900A KW with a 400 cummins, and a 20-25 ton tag trailer. Would a combination like this work? Be safe? Be sensible for moving the dozer? Or should I look at a day cab road tractor and a 25-35 ton lowboy? Looking for advice on the best/safest/sensible combination. Any advice is appreciated.
