Hi Sara
I have a self build conversion.
I couldn’t live without the toilet, which is so great to have when you really need to go.
I wish the bed was a permanent bed at the back, rather then one I have to make out of the seats each evening.
I wish it was fully electric in the living area rather than the gas cooker and heater.
On the road the biggest problem is the van is big and hard to park, but this also gives good space in side.
