Hi and welcome!
I'm not seeing ANYTHING like what you describe in the HiLo brochures for model year 1995 in 22ft length. However, there IS something very close to your description in a 26ft Voyager. It has an optional model with twin beds, bathroom in the middle, and dinette in front. You can see this model here: https://www.hilotrailer.com/home/then#1990
- It's in the Classic series for 1995. It has a dry weight of about 5000# and a tongue weight of around 750#, which will be your real limitation. I'm sure your truck can "pull" the trailer weight, but the 750# will put a heavy load on your truck's axles. You WILL need a Weight Distributing Hitch (WDH) to transfer about half of that weight to your truck's front axle, or you will likely overload your truck's rear axle.
Possibly, the owner or seller is giving you the length of the "box" that you live in, which is the way MOST trailers are measured. HiLo measures their trailer length from the front of the towing A-frame, to the back of the rear bumper, which can add 3-4 feet to the "box" length.
Hope this helps.
