Oh, hell, just saw you already rejected ‘Mastodon’. Oh well, how about:
Vickers Armstrong Ayrton Mk IV (cockney rhyming slang for a ten-pound note, geddit?)
Vickers Armstrong Haulmaster Mk IV
Vickers Armstrong Veteran Mk IV
Vickers Armstrong Mastiff Mk IV
The British Army imaginatively calls theirs the RG 12. The Bedford was the standard in the late 30s.
How about calling it the Marlborough, after the famous general? (Wellington, of course, being used for a bomber in the War).
Vickers-Armstrong Constant Mk IV
Vickers-Armstrong Praetor Mk IV
Vickers-Armstrong Magister Mk IV
Vickers-Armstrong Proconsul Mk IV
Vickers-Armstrong Efficient Mk IV
Vickers-Armstrong Cockswain Mk IV
Cockswain is funny. You should put that in the “clean words that sound dirty” thread.
The Oliphant-Wittingtonsidebottom 9000. Type “B”.
Ooh, I was hoping it would be something like a little stream puffer cargo carrier. Then you could call it the “Vital Spark”. 
Way ahead of ya. 
:eek:…snicker…
So far, I’m liking “Percheron”, “Oliphant”, and “Mafeking”. “RG-12” is just a little too plebian. “Vital Spark” is cute, but not self-important enough.
The Trouncinator.
Too chi-chi.
Too busy.
Too…too…California.;)

I saw what you did there.

HMS Rantipole
Norton-Sedley tracker Mk-IV
Does anyone else think it looks like some sort of modern day conestoga wagon?
The Conestoga IV would be my suggestion.
