[Closed] Bike specific day van / stealth camper - brain storm

I had an Eberspacher in my lwb Transhit which was great- however two downsides:

1. You need to drill quite a few holes through the floor for air inlet, exhaust and fuel supply.

2. They are noisey buggers, the fuel pump clicks and the inlet and exhaust both need silencers fitting to not annoy fellow campers/yourself!

I've got a propex, much quieter than the Eber on my work van.

Rarely use our heater. Occasionally in the morning in the colder months, and even then only when the GF is with me.

Decent sleeping bag /duvet at night, a down jacket and a cup of tea when you're up.
