I appreciate your dilemma, da7id. Though our dog is smaller, when we purchased our Airstream early this year we had parking space concerns at our condo and we loved the almost new Jeep GC Ecodiesel we were committed to use as our tow vehicle. We really like the 32 mpg and almost 800 mile range when not towing, and the tow capacity was ok at 7,200 lbs, but the tongue weight limit of 720 lbs eliminated our first choice, the 25 FC. The dealer tried to assure us (incorrectly) that our TV could handle the 25FC. But, as many have said here, the listed dry tongue weights are far from accurate and this is a very important consideration regardless of the hitch used. We went with the 23FB and after 15,000+ miles, including many mountain passes, are pleased with the combination and accommodations. We do use a tongue scale to check loaded weight, but even when we packed for a 95-day cross continent trip were well under the 720 lb limit. We use an Equalizer hitch that weighs about 85 lbs. I also confirm weight and distribution using CAT scales.
Good luck with whatever decision you reach!
