Not at all but you haven't specified the license class or use. I guess you mean one that can be driven with normal car tax and license.

The classic Range Rover, 110 and 90 all can tow 3,5 tonnes with overrun brakes and are licensed as dual purpose. There are various tacho and operators license requirements for some commercial use. They can also tow a 4 tonne trailer with service brakes. GTW must remain below 7.5 tonnes for most licences.

Limited to 1.5 tonne towing capacity IIRC

The heaviest, try something like a vintage Scammell contractor good for a couple of hundred tons or so.

Run it on LPG.

My granada derived limo was plated for an MGW of 3.7 tonnes, and was excellent for towing a caravan, I hardly noticed it was there. Not much good off road though.

Lets make this clear, a 101 can tow 5 tons ... but can't stop it for toffee! :-) Legally gs models are plated at 2 tons (earlies are 1.5).

I'd get a 110tdi hardtop. Stable and economical towing that sort of weight and will eat fields for breakfast.

The one big disadvantage is they're not shaped like a 101 ... :-(

From LR website

New 2007 Defender´s best in class towing capability, with a braked trailer of 3,500kg and best in class load carrying capability with a

3,500kg gross vehicle weight (GVW) demonstrate Defender´s all-round capability. And with a strong, rigid chassis specifically designed to handle heavy, awkward loads new 2007 Defender can tow more and carry more across more extreme terrain.

No it was the MarkIII though the scorpio has been converted as well. Wonderfull V6 engine, dunno how it would do in a landie though.

On or around Tue, 25 Sep 2007 20:47:21 +0100, "GbH" enlightened us thusly:

basically, add an LPG system and feed LPG into the diesel engine in addition to diesel - the idea goes back quite a long way, and is also known as fumigating.

However, it's not for the novice or the faint-hearted. I gather it's quite easy to get a lot more power for not very long. Normally, you'd look for a modest power hike and try to keep the running costs about the same. If you turn the diesel down and use a fair amount of LPG you can reduce the running costs, since LPG is cheaper. You're not likely to achieve that at the same time as boosting power.

The other option, easier probably, is to fit a larger intercooler and turn up the boost and the diesel. You might need a larger intercooler to fumigate successfully anyway, as the problems tend to come from combustion temperatures.

most "normal" turbodiesels will produce more power than stock by increasing the boost, thereby getting more oxy into the combustion chamber and allowing you to burn more fuel. However, you reduce the engine life, and if you do it too much, you can reduce the engine life to days...

has a V16 cummins, which has 4turbos and produces 2000hp, from something not that much larger than a truckengine. It's impressive... but it uses specialised coolant and they reckonthat if you run it on plain water it'll die fairly quickly. Also, even ifcorrectly looked after, it's got a typical working life of about 5 years.

Not difficult at all - and there is no extra wear on the engine and no temperature increases.

You fit the smallest lpg system you can get hold of, but DO NOT go for vapour takeoff with a regulator. You need a small spigot type mixer. An lpg flow meter is also useful for fine adjustment.

You can control the LPG solenoid either by a microswitch on the throttle or by a pressure switch from turbo boost.

Forget about economy and fuel savings - you really won't make any.

Somewhere I did have a load of data from test runs on my 200Tdi. It's a while since I played with it.

I believe there are more sophisticated systems on the market now. You could try car autogas in Stoke-on-Trent.
