suitable accomodation for VISA?

I'm planning to move to the UK by the end of January on a fiancée visa, and part of the VISA entitlement is that we have suitable accomodation. My question is, would a static 37ft long 12ft wide 3-bedroom caravan with full facilities be accepted as "suitable accomodation" for myself, my two boys and my fiancé?

That wont be a problem.
I think they're really just trying to make sure that you're not moving into a 2-bedroom flat which already houses 10 other people! 

Thank you
