Great thread from the non-big-truck-only crowd.
I started a similar one seeking input from other Cayenne owners earlier this year, before deciding to seriously look & pull the trigger on a well maintained "gently used low mile" 2006-10 V8 powered Cayenne S. I can't see ever recouping $20-30K in the extra cost for a 2013-14 Cay-TDI in the extra mpg for a TV which we'll use a few times a year towing & as a 3rd car, so a nice used Cay-S with a normally aspirated V8 for our 3000# +/- Avion will be more than adequate! ;-)
We'd hoped to be Cayenne S owners in time for the big Pismo Beach CA vintage trailer rally last weekend, & had several great prospects back in Jan-Feb, but my aunt got sick in hospital etc. & passed a couple of weeks ago (she had no kids so I've been next of kin in charge of stuff).
So I'll have to restart the search in a few weeks when I get caught back up.
Our rig was set up for initially towing with various rented TVs & maybe eventually a mid-size SUV - so I set it up with:
1. a Tekonsha RF wireless brake controller - essentially an A-frame mounted Tekonsha Prodigy with a wireless controller handset that plugs into the cab's 12v
outlet/cigarette lighter & eliminated reaching for the under-dash box brake boost button, since it sits at hand in my lap!
2. a Hensley Cub WD/AS hitch (their smaller 6000# & 600# HW unit which sells for $1300-1700) - & I'm 100% pleased with it's operation in towing & that all WD gear stays on the TT & no levering up spring-bar chains!
AS for the back half of our rig - the Avion T20 is 21'-6" L with the 4" square rear bumper, plus the Hensley adds it up to about 22'-6"; & it was listed by factory docs as 2680# & my calculations on changes by the PO's restoration/mods & fluids/capacities & all our stuff inside puts it at about 3000-3500# GTTW, with a known 340" HW on my new Sherline scale. I still need to catch time at a CAT scale for actual weight, after I can complete a few other mods which may change the GTTW &/or HW &/or distribution, latter 2 mainly by the customized folding rear cargo rack for the trailer spare & our bikes mounting to the trailer's rear bumper.
We've been renting since we got our restored vintage kin Avion T20 in July 2012 - including Ford F150 & F250, Dodge 2500 with V8 gassers & diesel, & Nissan Pathfinders with 4.0L V6s - but the trucks just don't fit in our narrow 1921 driveway space & narrow streets well, nor will my wife drive them - so the mid-size V8 SUVs became our target audience & finally zoned in on a used Cayenne S.
While the 2008-10 Cayenne S has the metal coolant pipe upgrade from the start & other upgrades in that Series 2 (or 1.5) version - we really like the 2006 continuation series Titanium Edition only & limited production "Iceland Silver" paint color (a light silver-blue metallic) only available for the June-Jan 2006 extended run of the Series 1 Cay-S - so I have to be careful to check that the coolant pipe & other upgrades were done on those.
For those unaware, unlike VW producing the 2007 Tauregs - Porsche elected to just extend Series 1 production of the 2006 as that Titanium Edition fully loaded with a bunch of options, & only available in Black, Red, Dark Blue Metallic or Iceland Silver paint, with either Grey/Black or Tan/Black 2-tone interiors. My guess is that these limited production models may
have the best chance to eventually go up in value later on as collectable Porsches - with that least common Iceland Silver being more rare, & since I tend to keep my cars forever - our kids may be able to recoup the purchase price in 20 years! LOL
I'll report back more on the forum once we have it & run for a while.
