Where are you going, what do you want to do, will you vacation close to home, will you travel the country, will you tow a small car, do you need to tow a large car (big family) or will you be towing your boat?????
I have always previously had gas higher end RVs, (for about 30 years). The Holiday Rambler 454, the Pace Arrows, and the last an Adventurer. All great coaches. All served the family well. All were purchased new. Personally, if my choice was a new high end gasser or an older diesel, I'd take the new gas RV. I really like my current Tiffin Allegro RED (rear engine diesel)38ft. It would definitely be above your price interest range. You could probably get a really well equipped new gas Winnebago or Tiffin (or many other brands) at or close to your price point. Other than the MH being much noisier on the road, especially on hills, having a rougher ride, and having a smaller tow capacity, they were great as far as livability, and camping comfort.
JMHO
Happy Trails.
