It may be that you didn't do enough research before buying and that a different layout would suit you better. We spent over a year looking for our first Motorhome and were lucky enough to be allowed to borrow both a small VW camper and a huge A class before making a decision. Like you we bought second hand and had decided that we didn't want a fixed bed as we wanted a compact vehicle. Other requirements were for an on board toilet, space for a dog, lounging area, space for cooking and food prep plus all the usual stuff. Having borrowed the A class that was our preference, it having a fixed bed that didn't encroach on the living space. However finding one in our price bracket was not easy. Our second preference was for a rear lounge, theory being that if the weather was OK we could spend most of the time outside and so leave the bed made up. In the end an A class Hymer B544 appeared at the right time and so that was what we bought.
Our other reason for wanting a Motorhome is so that we can get away for long weekends with the dog and just go where the weather is good. We have found that CL's and CS's are very cheap and convenient so you have the facilities you need and the security your wife wants (we have yet to try wild-camping and I have to say that I am a bit apprehensive).
If you haven't been totally put off I would wait for better weather and venture out again, try a few local trips over a weekend to get used to the vehicle and how you use it, then if it is going wrong you can always go back home.
:goodluck:
