We've had our Stealth 2313 since June and have been very happy with it. No major issues to speak of...just a few minor warranty fixes. We just recently downsized our tow vehicle from an F350 diesel to an F150 with Ecoboost. I have been very impressed with its capability. The suspension was the only real noticeable issue, much softer than the 350, but I added Timbrens to the 150 and it helped.
My trailer's yellow sticker states a dry weight of #6529. I have weighed it loaded for camping and it weighs right around #7300 with a tongue weight of about #1000. We do not haul toys, and only carry about 20 or 30 gallons of water; we usually only camp at sites with water, and electric hookups.
For us we mainly tow locally, with a couple longer road trips a year, maybe 1500-2000 miles a year. For this, a diesel just wasn't needed.
