If the leaf springs are on the underside of the axle, you should be able to flip the axle and mount the springs on top, then you wouldn't need as much of a wheelwell, I did this on my popup camper worked great. You should be able to bolt the frame of the shed right thru the frame of the trailer. I don't think you would have a weight issue. Doesn't sound like your going to be using it on the road. Tony

We use a square hard plastic/vinyl pond liner that I found at a yard sale. It fits perfectly in the back of our van with one back seat removed. I think it cost $30. which we feel was a very good buy as it had never been used. It's easy to put in and remove and keeps the van clean. Not sure how the new price of a pond liner compares with a cargo liner but it might be worth investigating.

Anyone ever converted a trailer for camping? Here's one example of a 6 x 12 cargo trailer converted like a tent on wheels with a few extra comforts like heaters and cabinets. 6 x 12 Cargo Trailer converted for camping There's a link on that page, in the first couple of paragraphs, that goes to a Teardrop Trailer site where a bunch of folks share ideas for making affordable camping trailers. Including cargo conversions.

We haven't lived in a camper while we built, but we did travel for 2+ years in a motorhome while looking for a home, land and what state to live in. In retrospect, we would have gotten a large, comfortable but less expensive fifth-wheel or trailer (which sounds like what you want to do) instead of the 45 foot luxury, expensive, used motorcoach we got. We were always too afraid of messing up the custom everything to enjoy it. If you are willing to live in a smaller space for a while, do without some luxuries, and you think you'd be content and flexible, you'll be fine. It can be enjoyable and liberating to see how little you need! If you take the opportunity to, you can make it a time to really slow down, simplify, escape the tyranny of stuff and take the experience for what it is and what it offers. The mistake we made was we tried to bring all our "stuff" with us - computers, exercise machines, a library of books - and it just got in the way and made it cluttered, physically and psychologically. Some luxuries you may have to be content without: baths (most have showers only), a big, fully equipped kitchen, etc. We stayed in hotels sometimes just to take baths! How much you enjoy it is more about your mindset than anything else, I think.
