Hi I have an Alphard rear conversion. I toyed with rear or side. I chose a side Kampa Motuin air awning. I got an awning rail fitted and it goes in a treat. We put the Porta Potti in the bit between Van and actual enclose area of Awning. Its great only wish we had waiting until the 2019 version as it now has an extension annexe that can be fitted for more room. We bought a trespass even shelter as we like to cook out away from the Van. Got an electric type slow cooker and a single hob burner works brilliant for us. Even tent works as kitchen and socialising if raining.
