Our convertible is obviously not 4wd. It is also very tractionLESS on anything that is not solid pavement. My 150' gravel driveway is an 8*-6* slope. Thanks for my 455 Buick powered all wheel drive '75 Jeep 3/4 ton pick'em up truck I have no problems manuevering our AS around the property. I could consider it as a TV but the single digit gas mileage discourages that.

Is it a necessity? No, but as others have stated, it sure is nice to have. I have been at some campsites where you had to back the trailer up a decent slope going uphill that was not possible without the 4 wd engaged. Have also been stuck a few times in the grass, that took 4 wd to get out.

My truck is 4wd because i also tow a boat and the ramps can be very entertaining in the busy summer months watching some of the 2wd try to pull their cooler laden toys outa the water. If you go with 2wd invest in an air locker like ARB for the rear axle, its money well spent.

I'd get it because it is not that much more expensive and when you need it you really need it.

I think it will make your truck easier to sell when that time comes, too.

How about all wheel drive, I have Lexus GX470 all wheel drive, replace the 4runner which was rear wheel drive. The tow capacity for Lexus is 6500 lb because it weight 5,500 lb where as 4runner was only 5,000 lb and towing capacity of 7,200 lb.
I have not gone to any off road, but it may come handy when driving to Alaska

We opted for a 2WD on our Tacoma since we don't do a lot of off-road...but we can lock the rear differential, which has come in handy a few times to get up a grade in a campground.

I've had 4wd since 1988 and would never willingly have anything but.

I tried to move my first 31' Excella with a 2 wheel drive on wet grass, almost level very slight slope involved. Got stuck, not in mud but on top of the grass. It would not pull up that slight slope. I tow with 4wd self locking differintial, always.

Yup - I wouldn't even consider 2WD; won't be buying a truck with rollup windows, AM radio or manual door locks either...

Get a 4x4, and make sure you get the posi traction rear end too, it is amazing how much that can keep you from getting stuck in.

Like wet grass.

Actually - you do not want Posi-Trac as the wheel that slips gets more and more of the power....

One want's a "locking rear end" - that's the key for 4x2 or 4x4!

My BMW X5 is "all wheel drive". Your Lexus GX470 probably functions like my X5 in that the differentials are "open", which means that they do not have positraction or locking capability, BUT instead use the anti-lock braking system in conjunction with the computer to moniter wheel slip and apply the brakes (pulsing them) to any wheel which is spinning, thereby transfering torque to the non-spinning wheels which have traction.

These systems are probably very adequate for 99.9% of the traction events we get into with site issues. Just don't ever try to remove a really stuck TV/TT combo with an AWD (All mfrs included). You will burn up AWD transfer case clutches as well as brakes. AWD is a great system for on road vehicles which see normal and occasional traction issues. If you do a lot of fire roads (muddy) or are really stuck, call for help. This is where a true 4WD is the only answer...with at least a rear LOCKER, not limited slip or posi.
