You guys should put together an audio CD/DVD of your experiences like Top Deck Daze.

Thanks again for sharing your experiences.

I feel more confident in the capabilities of a robust 2x4 now and so I think I will put an offer in for the ex brinks 18t security truck pictured above. It really is quite amazing inside, I’ll be sure to post some photos if I bring it home.

The box is stronger than anything I’ve ever seen and looks like it would well outlive the chassis.

Internal modifications will be a pain given that everything is constructed from hardened plate steel but I have been offered a great price for it due to the fact that it is fairly useless for most purposes. The box is too small for anything but the heaviest cargo (gold bullion), the security systems have been removed so it is no longer useful as a top spec security truck, and the cab cut through means that it would be a difficult to return to chassis cab form. As a robust RTW motorhome it seems built for the job!

Look out for the guy in the most over-secure camper ever built.

And probably the heaviest!

Twin wheels
 

Hi, interesting conclusions, and perfectly valid.
I admit basing any truck choice more on feeling and emotion than on the practical reality discussed here (I haven't taken the plunge yet Quintin, more nest making...but goodness how I yearn to).

The following links to the builds of some well pimped 170D11 seem to imply that you can simply take off the inner wheel on a twin set. I supposr you would have to downrate the max vehicle weight...

A lot of work went into those; makes you think that a Maggie isn't such a bad choice, Pity they're impossible to register in France

Weird, in the post, the links have the same title, they point to 2 different threads
