The lack of a toilet and bathroom (sink) is not a problem (maybe for some) as you may be a campsite user and therefore have everything needed there.
We do not use campsites (or at least we try not too) as we have a portable loo and wash the van. This took a little getting use to, but it is not an issue.
Last year we travelled around France/Germany using Aires/Stellplatz 90% of the 6 weeks and 10% on campsites or showers/washing/toilet etc.
What we really like is the ease of parking in small towns and villages in a normal car parking space and no one gives you a second glance.

Works for us as packs away so small, but takes 2 minutes to make ready. Bag it.... tie it...... bin it..... perfect. Fits where ever you want it and no smell with supplied chemicals however we use cat little which works a treat. Can take my 97kg but think it goes up to 150kg
