Need to look for it

Our desired style of travel has changed, and we are ready to sell our baby that we have sunk years of blood, sweat, and tears into building.  

We hope she’ll make someone else’s travel dreams come true!  The size of this bus is RARE and is absolutely perfect for 2 travelers and several dogs. If you’re familiar with bus sizing, this is a 6 window short bus with a van front (so easy to get mechanics to work on it).  The bus is 24′ and the living space is 14′.   There’s both a short queen in the back and a pullout twin/couch.  The kitchen is nice and roomy, and there’s even a decent size shower framed out.   She has been thoroughly inspected by multiple mechanics, including this year, and they all remark on how clean and well-maintained this bus is. There’s no rust on the undercarriage, and she’s all in working order.
