Prunella would not qualify as a trailer "queen" - so I guess she's just a solid little tramp that uses an enclosed trailer as a convenience. We like to stay at bed and breakfast facilities where interesting tour possibilities for the Model A are just down the road or around the corner. We'll seldom be more than 50 miles from the trailer and, in the event of a breakdown, all we have to do is go get the trailer and load Prunella in using an electric winch. There are literally hundreds of places of interest within a day's drive, using the truck and trailer, but only a few within reasonable driving distance for the Model A running solo. Too, many of the roads along the way to tour sites pass through boring areas and/or require driving on freeways or through large cities. The trailer also provides overnight security when parked, the protection from hail and other hazards on the road, and a reasonable complement of tools and parts to effect minor repairs - out of the weather. It works for us, but I haven't read too many comments from others about this method of touring?
Let me start by saying I guess this is one of the few times I actually agree with Bill.
The term "trailer queen" --or the term of "stretcher" used in lieu of a trailer (that one courtesy of John Buttera & Gray Baskerville) is typically used as an arrogant & provocative term to antagonize & belittle someone else's vehicle. I have used my Hauler to transport my antique cars to places such as Florida, Savannah, GA, Rutland Vermont, Rochester, MN, Mt. Rushmore, SD, ...and on & on. I don't care if someone makes fun of me or not. I know that my vehicles run like they're suppose to. The bolt truth is just like said above, a trailer just opens up possibilities to do/see more.
Getting back to your topic of trailers, there are many hobbyists in the Model-T circles already doing exactly what you have thought about. Many of them have not gone the $70k 'Toy Hauler' route, but instead are building their own for probably ¼ of the 'Toy Hauler' costs. I put on a tour in Crossville a few years ago and belowis some pix of one that came down from Canada. If my memory serves me correctly, the builder/converter put in a 2"x12" high sub-floor in the front 10' of the trailer to house pipes and holding tanks underneath. In the very front of the trailer, there is a Queen sized bed mounted on top of a large wood storage compartment that raised up and housed a 100 gallon water tank, the water heater, and other stuff. On the curbside next to the bed was a full length closet, and moving rearward next to the closet is a small shower/toilet combo. Beside of the shower stall is the trailer's side entrance door. Across from the shower & closet is a kitchen with sink, refrigerator, and stove. Cabinets over that. On the rearward edge of that 10' long platform is a large table on posts. They had two shorter stools for sitting on the platform side, and taller stools for the trailer floor side where four people could eat a meal together.
Behind the platform was a 14' area of the trailer for transporting the car. The entire trailer is insulated and there is a roof-top A/C unit. Also with the rear door down, they had a net that snapped onto the rear door opening so friends could sit inside the trailer w/o bugs or mosquitos being a problem. They also had a fold-out awning on the exterior of the trailer (street side). They and many others out of the Michigan/Canada area use these type trailers 10-12 weekends a year for weekend get-togethers with their Model-Ts where they tour during the day and fellowship/camp at night.
My personal opinion is if someone spent about $10k on a new properly spec-ed out 24' enclosed trailer, and then had another $7500-8000 budgeted for furnishing the interior themselves, they could build a really nice unit that wouldn't break the bank, --and wouldn't need a $65k truck to pull it. BTW, imagine how impressive a trailer like this would be if it were built with a 'Victorian' theme inside with woodwork, antique lamps converted to 12v LED, covers on the appliances to make them look vintage and such. That way your Bed & Breakfast would be exactly where you wanted it to be!
