A few of the Jayco Eagle HT models are shorter. They're probably a bit over your price range for brand new, but you may find a decent used one that's just a couple years old.
We ended up with the smallest Montana High Country because of the gen prep option, but I really liked the Grand Design Reflection 150 series. The layouts seemed efficient, but still short in length. We probably would have gotten one if they offered Gen Prep as an option. We had similar requirements to you for the slides... accessing the bathroom/bedroom and being able to get to the fridge. We can't get to the pantry but that's OK most of the time.
