This from Larry Shapiro:
Alexis delivered Long Grove‘s new Tanker on Tuesday and I stopped by to get some photos. Specs are 2013 IHC 4400 – 2013 Alexis 1250/1850/50A – so#2204
This is replacing Engine 55, not the current Tanker 55. The new unit may run as Tanker 55 or Tanker 56 depending on the situation.
More photos are HERE.
