The four cyl. Works fine. Yes they are very slow going up a hill. I run
with a bunch of guy's who run V8's . Every year on are trip to Silver
Lake sand dunes I have to tow one of them out. Sure I dont fly up the
hills like they do . but its still fun. I also drive mine the 21/2 hour
trip to the dunes and drive back home. They trailer there Jeeps.
Anouther guy I wheel with is big into mud. I go with him alot also. I
get stuck just as much as him with his 8. I have a winch so it's not
that big of a deal . I'm more into trail rides. So it works good. Right
now i'm changeing gears to 4.88's . That will really make a huge
diffrence. Hope this helps.

48 *****'s 4cyl

A well designed air cooled vehicle installation and the VW Beetle are
in fact two different things, although later examples and US
aftermarket upgrades did help a lot.

A Deutz has a big blower and is designed for stationary as well as
vehicle use. In a Jeep I think it would be fine for crawling. As far as
contaminated cabin air-use electric heat or a SouthWind heater and be
done with it. The noise a Deutz makes has to be heard though...on
second thought, American offroaders, who are more interested in showing
off than getting anywhere, maybe this would be a plus instead of a
minus.

The 2.5 is fine for what you need IMO but if you must have more power just
buy one with a 4.0 or you will be in upgrade hell spending more than you
would just getting the 6.

"As far as contaminated cabin air-use electric heat..." How many watts do
you think it takes, to heat a vehicle cabin to a comfortable temperature, in
a reasonable time? You can arrive at a rough estimate using one hundred
watt light bulbs, electrical pig-tails, and a couple of extension cords.
You may need to plug them into separate circuits. You will wind up with a
two thousand watt alternator, at least, to satisfy most people's cabin
heating requirements.

Fuel powered heaters are effective and efficient, but they are a bear to
maintain. You can find a radiator repair shop, or buy a replacement heater
core, in most small towns in the U.S. or even in Europe.
