Hé, hé... the great and wise Man has spoken. You are right, Geoff : "Que chacun fasse comme il lui plaît" (let each do as he wishes)...
I'm not sure if "being a little cracker" is a compliment. I know "a cracker" (a good-tasting chip, but a bit salty and spicy), "a fire-cracker" (a funny trick that makes "bang", un pétard) and "a cracker" as an idiot, a stupid boy...
I suppose you use the 1st or the 2nd meaning, but as my wife often says that I'm "un emmerdeur" (a kick in the ass, a ballbuster), or "un vrai Basque" (it is equivalent, as if you were saying : "He, sure, is an Irishman !")... why not ?
I really like the Dust conversion. The quad is OK in size and the big material transport truck is good too. I am much less convinced by the Humvee : too small in my eyes. I've only seen this kind of vehicle once, and it was a really, really big thing (next to my car and I). But hey, I'm a (military) Land Rover lover !
As for the hovercraft, with martial paint and markings, with a crew of Navy-Stormtroopers, why not ? The good idea is not far.
