Yes.  Ref TM 11-487A (AKA MIL HDBK 161) 1959 edition "This equipment 
consists essentially of Radio Set AN/GRC-26A mounted on a 2-1/2 ton cargo Truck 
M35 and a trailer mounted Power Unit PU-290/MR.  All components except the 
power unit are contained in Shelter S-69/GRC.".  If you dismount the shelter 
and contents and set it on the ground, you have an AN/GRC-26A.  Legally, 
anyway.  FWIW, AN/GRC-26 was in Shelter S-55/GRC.  S-69 came with the A-model.  
Possibly due to changes in the equipment load.  11-487A describes the GRC-26 
in similar terms but does not specify the truck.  I guess in Logistics terms 
it had to be requisitioned separately.  :-)

Yes.
