Following helpful feedback [no pun intended], I have decided to group all the Salvation Army Catering Units together on one page.   The vehicles can all work anywhere in the North West Area that the Salvation Army currently covers and are not restricted to any particular Fire & Rescue Service.

The Cheshire SACU is Mercedes PN63PDO  and was seen at its base, 19 January 2019.
This vehicle is currently based at Lymm Fire Station, callsign E28S4.

 Catering Unit MM51OZP was seen in Openshaw, 19 February 2017.
This vehicle is currently based at Salford Fire Station as G58S4.

The first new SACU to enter service was Iveco PO13FLL with Greater Manchester.
The new vehicles will be identified by callsign with this one being G35S4.
This vehicle is normally based at Chadderton Fire Station but currently operating out of Hollins Fire Station.

The interior is both larger and higher vastly improving working conditions for volunteers.

The latest SACU for Lancashire, Mercedes PE63TZX was seen in the yard at Wesham Fire Station, 22 Janaury 2019
This vehicle is normally based at SHQ with callsign L52S4.

The SACU for Merseyside CK06XPO was seen at the Engineering Centre, 10 May 2011.
It is normally based at Kirkdale Fire Station.
