My trailer is larger than what you're looking for, but for the two of us, it's as near perfect as a RV is going to be. We have a 2017 Jayco Jay Flight 23RB. It's 27' from rear bumper to the front of the hitch.
It has no slide, enough room for the two of us. Lots of storage. One thing it doesn't have that would be nice is a pantry. However, we just use one of the tubs under one of the dinette benches that came with the trailer for heavy food supplies.
Has a large wardrobe in the bathroom. Needed when going on 8800 mile trips across the country,
If need be, it can carry 80 gallons of water, and has 40 gallon gray and black tanks.
The Jay Flight models are the old style, "stick and tin", but it works quite well for us. It's small enough that we've had no problem keeping it cool enough with one 13.5k BTU A/C. However, if I were ordering it, I would have gotten a 15k BTU A/C.
And at 6500# GVWR and 27' long, it's not too heavy or long for my 2014 F150 Supercab long bed with the Heavy Duty Payload Package.
