Car is bougth and first fuel consumption test done and it works much better than expexted:

Test on my stock Touareg 2.5TDI with 6 speed manual gearbox This weigths around 2000 kg and is quite big car:
80 km/h= (10km average,dry)
100 km/h= 7.3 l/100km (20km average, wet road)
120 km/h=8.8l/100km (20km average, damp road)
140 km/h=11,0 l/100km (20km average, dry)
160 km/h= 14.1 l/100km (20km average,dry)
180 km/h= 18.9 l/100km (10km average,dry) Was not anymore super relaxing speed at nigtht. Top speed is around 200 km/h.
You can do a search based on Airstream trailers and Touareg. High numbers. As always, it isn't weight, but shape. Published writings by Canadian RV dealer Andrew Thomson. See Can Am RV website and RV Lifestyle magazine.

But a trailer over 7000-lbs?. At a 10-15% tongue weight of 700-1000-lbs, one needs to have around 400-lbs Axle capacity at both ends in using American/Canadian style weight distribution hitches. (The Euro standard low tongue weight makes for increased instability).

The trailer FE test is simple enough, though. Load the T-reg up to weight capacity. Run a 200-mile roundtrip from a fillup and then weigh on the truck scale showing both axles separately, as well as gross. Drive at the same speed at which one would be towing. Use cruise control.

Deduct 30-40% based on decent aero efficiency. 40%+ for a bad shape. 50% for bad shape plus stop and go. Etc.

The difference between a penalty of one-third to one-half just isn't meaningful unless the towing miles constitute a significant fraction of all miles travelled. That you need to answer first.
