Hi Ed
I changed last year from a Sorento to a Isuzu Rodeo 3.0 double cab mainly due to company tax reasons, and can confirm the Rodeo makes a great tow car.
When fitted with the body coloured cab cover it looks like, if not better than other 4x4 type vehicles and swallows huge amounts of stuff, and we have had no trouble on site with it being a commercial. Also, the ride improves with weight on the back of it, but little difference between the Rodeo and Sorento when solo.
No problem with lack of power, and fuel comsumption at least equal to the Sorento, even though 3.0 auto. I also find the long wheel-base makes for a very stable ride when towing. Whatever type of double cab you choose you won't regret it. I would not to back to a 4x4 car now.
