That's all kinds of wrong, buy a small tent & Stove and just take the Abarth 
(obviously not in this country when non stop rain would make it miserable
)
Technically its quite interesting how it works, how does the steering work, does it just drag the fronts around as you corner?
Braking system looks like that on a SanKey trailer 
I've done that too, you can fit a 3 man tent, 4 pillows, an airbed and pump, 2 large sleeping bags, a medium sized stove, and a lantern in the boot if you spend 20 minutes arranging it

And the steering is so amazingly simple... You put the spare key in the ignition, and turn it about half a click, before everything turns on, it takes the steering lock off and allows the wheels to turn whenever the motorhome does, it sorta follows the curve the motorhome takes.
As for the insurance, I'll have to get back to you on that, its my dads motorhome, he does the driving
