Given what you want to do, it may not exist, at least not unless you luck on the deal of the decade. The first requirement for what you are desiring is reliability, you need to know that there is a good chance you will make it to your show dates and not get stuck on the side of the road waiting for weeks for engine repairs, etc. Anything you find in your $35,000 price range is going to be older, probably over 15 years old, and if maintenance has not been kept up will nickel and dime you to death, often being stuck in the shop somewhere. Getting a motorhome repaired is not like taking your car into the shop for the day, even small jobs often take a couple of weeks to be scheduled in, so if you are not a DIY'er a 15-20 year old motorhome on limited funds is probably a bad idea.
Now if you just want someone to point and say buy this one, you are not likely to get that without providing a lot more information, like how many people to the bed, anything you find even close to this budget will likely have a queen or king size bed in the bedroom, plus a 2 or 3 other sleeping spaces for 1-2 people each. If you are looking for separate beds for 5 people in a class A diesel pusher, you are getting into needle in a haystack territory.
Now given your budget I would probably be looking for something like this 2007 Safari SImba toy hauler which sold last year at PPL for $38,700 https://www.pplmotorhomes.com/used-rvs-for-sale/diesel-motorhomes/2007-safari-simba_rv-30874 you can see PPL's sold coaches for the past 2 years and price they sold at here https://www.pplmotorhomes.com/diesel-motorhomes-sold?pageSize=300
The Simb FD is a front engine diesel, this one is a toy hauler model with a bedroom / garage in the back, it has 2 ceiling drop down beds one in the front one in the garage. I think it had an option for a double drop down bed in the garage, that would be giant bunk bed style. Either way you could add a sofa bed or similar below the garage drop down bed, and sleep in the drop down bed with it half way lowered. This combined with the dinette bed upfront plus the 4 captains chairs probably gives you better sleeping and travel space than most other options in this price range.
