Where was it?

[Liverpoollass]

I recently read on here about how to tell if it is possible for a motorhome to be uprated/specifically which ones to put on a shortlist prior to travelling to possibly purchase. I recall that there was advice about maxi chassis, but think there was some other advice..Can't find the post now, can't anyone help?
thanks in advance
