We've been renting since mid-2012 everything from:
A mid-size SUV 2013 Nissan Pathfinder 4.0L V6 3x (not the new ones, but the older truck frame-on-body type) & they also had a V8, as did the Toyota 4Runner V8 & Land Cruiser V8 (also in that mid-size range, but we haven't rented any of them yet.)
To several full size pickups, including: a 1/2T 2013 Ford F150 Extended Cab/6' Bed with the V6/Auto, 2 - 3/4T Dodge Ram 2500 Crew Cab/8' Bed with the 5.7 V8 & 6.3 V8 Hemi & both Autos, a 3/4T Ford F250 Crew Cab/8' Bed 6.1L V8/Auto.
The F150 & first time Pathfinder were "bare ball" towing without Weight Distribution (WD) nor anti-sway, & the Pathfinder was a white knuckle ride over 55 mph, but the F150 had built-in anti-sway & was pretty good.
After the Pathfinder E-ticket ride - I got a Hensley Cub WD+Anti-sway hitch (sim. to their Arrow & Pro-Pride PPP hitches - more stuff for you to research & get everyone's opinion/preaching), & we're very happy with it since then on 2x Pathfinders + the 3/4T trucks. ALL were jacked up 4x4s.
All TVs were gas powered & all performed the task well on both flat/rolling & mountain pass terrain, but our 1960
Avion T20 is only about 3000-3200# max. wet & loaded - so net near what your new 25' AS will be. So keep that in mind.
, the 27-30' long truck + a 21-22' Trailer = a hitched rig of about 50' Long ~ & us climbing 6' high up into a jacked-up 4x4 behemoth 1/2 or 3/4 ton monster - was just uncomfortable in use & ride, handling & parking ~ plus I can only open the beasts' doors 1/4 or 1/3 of the way in our tight driveway ~ not to mention that my wife will NOT drive one hitched nor bare!
So given our driveway space constraints, narrow streets, tight campgrounds, non-towing driving preferences, etc. - the mid-size SUVs fit our needs
best, & I'm now looking for a 2006-10 gas V8 powered Porsche Cayenne S with 7716# towing capacity & 770# hitch wt. (with WD - 500# & 500# on the ball, & this is the same rating on all engines of both the Cayenne & twin VW Taureg - except the Hybrids).
If a Cayenne or Taureg tickles your fancy, then there are several topics on here for that vehicle set (including mine), as well as for BMW X5, MBZ ML/GL, etc., as well as the big pick-ups, & just about anything else.
In addition to looking/asking on here, once you narrow to a few or 1-2 prospects, then also go the the websites for owners of those vehicles, & read up on what they do in towing & ask questions there too.
You - & your wife/SO/GF/Family - will need to figure out what fits YOUR needs best, & renting different ones can help, but the tow vehicle rental field is limited in who will let you rent what & actually tow with it!
You'll soon see that there are 2 camps out there - the "only tow with a truck camp" (i.e.: full size pick-up or SUVs) - & the "we tow with a 'not-a-big-ole-truck' camp" .... & anything but what they espouse is heresy!!
But just get what fits your needs & check that the towing capacity numbers & set-up are within that vehicle's limits & safe!
Good Luck & Have Fun!
