It's impossible to give any advice without at least knowing how many are travelling, your expected touring range, using sites or off grid, budget, licence category (C1?), fixed beds?, preferred length, needing to fit a bicycle/scooter/moped rack? etc. etc., so come back with more 'personal' detail and a clue as to which motorhomes take your fancy.
If you buy in 6 months time you'll nearly be in winter so it would need to be fit for low temps.
As mentioned above, look at the Buyer's Guide on this site.
