I am driving around with trailer pretty much and its boats from small to big, i am driving a Chevy Tahoe with the 5,3 liters Vortec automatic petrol, its not the most economical car when it comes to fuel, insurance etc etc but in the long run i feel that it is worth every sent if you look to the comfort.
Sweden is a long country and its not uncommon that we trail 1000km.
Same car with a diesel would be a better choice than the petrol.

We have one of each, a manual L200 and an auto X5. For pure towing the auto is much better, much less strain on the clutch, transmission etc. Pulling away on a hill with a boat on the back and the clutch will smell on the L200. The l200 is more of a tool off road but purely due to it's more suitable tyres. For towing-Auto.

Well I owned a Peugeot Auto with the 2.1diesel, 46mpg cruising. My wife's wee 1.9 Citroen auto gives 44mpg.

Also the Discovery TD5 auto was criticised for being slow(ZF auto) at first so they remapped it which gave it similar performance to the manual - result 22mpg instead of 30.
I happen to own one of these. You are wrong.

My main vehicle is a Jeep CRD auto and it returns 35 cruising and 25 towing.

Jackwabbit's comment about never quite being the correct gear when towing can be valid. My 3.9 petrol RR was like that. It had to reach 50 to get into top gear. A tad lower and it would pop out. My older 3.5 RR was excellent. It changed into top (3rd) at about 35 and stayed there unless the throttle was opened wide.

I have the same "hunting" problem on the Bighorn and it seems to be a design issue making the box overly sensitive to throttle inputs. In the case of the Isuzu there is a speed sensor which controls these things, and people who have changed them out report calmer shifting performance. However, I agree that for towing, an auto reigns supreme and it's good off road also, especially if you have toys such as re-programmable shifts, hold-in-gear etc etc. Most engines and drive train components last many times longer in an auto than a manual. In this day and age of technology, I see no reason any more for manual g/boxes on the public road.

A question for those people with "hunting problems" - do you just leave it it Drive or do you bother changing down and using it like a manual???

No matter, it's still throttle sensitive whichever gear you run it in. Dropping a gear merely holds it in a lower gear with 1 change below that (for 3 speed boxes). I suppose if you dropped it into 1st gear you wouldn't have any problems with the box changing gear ever. Problem solved.

Most modern 4 speed autos use top as an overdrive and you should lock it down into 3rd for towing - if it is still hunting between 2 and 3 you have to either speed up or slow down and lock down into 2nd - the constant hunting is what causes heat build up.

It is all down to driving technique and it is suprising how many people just leave an auto in D and let it get on with it - they never bother to change down to save the brakes either!!!

Obviously I drive vehicles a bit harder than you.

How can you blankly state "you are wrong" because you own ONE of these??? I had BOTH the manual and the auto a short time apart - ok maybe I drive harder than most but I drove the auto the same as the manual - and there ARE differences.

It's all down to the Auto gear box. Our BMW has an "Adaptive" box which can be programmed for driving styles. With the boat on the back it is perfect. It's a five speed auto, it'll go up a known hill a gear lower with the boat on than with no boat, just like a manual. Dab the brakes and it kicks down going down hill to give engine brake which takes a bit of getting used to, clever though. I may add that the box was replaced at 23k miles due to a fault .

Modern electronics make people SO lazy!!! Yes they do work well but you can get just as much - if not more control by actually moving the stick yourself!!!

You are the 3rd person now I have heard that from!!! I take it you mean the X5? See if that had been a Range Rover by now people would have set up a website to destroy their image!!!

I have driven the X5 several times and was very impressed BUT what is it trying to be? It is too high to be a sports car but there is no way it could ever be called an offroader!!!
