With s huge amount of difficulty, factor. You used to be able to get a policy which you put a deposit down if your full time travelling, but that was a substantial amount (around 15k)
OP Here is a C&P I found inc web site you can use where someone else has asked the same question
"According to
http://sn.im/dvla_register (redirects to direct.gov.uk)
you need to provide one of the following proofs of address:
* utility bill valid within the last three months eg gas,
electricity, water, landline telephone
* bank or building society statement valid within the last
three months
* medical card
* council tax bill for current year
I guess that you'd get your bank statements sent to your mailing
service. So if you didn't mind giving the nosey so-and-so's at DVLA
access to your personal financial information and your mail forwarder
address didn't look like a PO box, you could get away with it.

and
Perhaps it depends on who you talk to at DVLA. However, in the notes
on the back of the New Keeper Supplement of the V5 for each vehicle I
own there is the following emboldened text: "Please note that PO BOX
addresses are only acceptable for companies and corporate bodies."
Each time I've talked to DVLA on this matter they've told me that the
address has to be proper bricks and mortar.
That postal service has now opened their new website, which can be found at
http://www.simplemailbox.co.uk/ and has dedicated services to the likes of
people living in motorhomes. bank accounts, credit cards etc
are all registered there, and when I spoke to them the address was
acceptable because it was not a PO box. I don't think I had to send
evidence, they just accepted my word as I recall.
You can then give them a post office to you and have the mail sent post resterante (thats not how its spelt) you can do it 3 times at each post office i think, its free you just need to inform the post office before hand and take it I.D."
