Perfect answer!
You compare the LC to a Honda? I worked on Hondas for 18+ years giving feedback and design ideas back to the company and during much of that time I had a Toyota in my driveway! Honda builds a great car but second best is still just a close second. Hondas are reliable but soft and fragile. Only Toyota can build a Toyota!
As to the rest of the builders, the Japanese (with the exception of Honda) use real steel in a truck. They are solid. My last 4X4 was a short Montero, about the size of a Jeep CJ7. The Montero weighed in at 4210 pounds without fuel, compared to the Jeep at 2500 +or-. The Montero's weight is similar to that of a full-size Chevy 1/2 ton 4X4. It is built from real steel, not soup cans.
The LC 80 is more of the same at 5700 pounds. It is basically a tractor with air conditioning. Weight savings are great for soccor mom wagons, but it will hurt you off-road. Weight is what keeps the wheels on the ground as well as preventing broken frames and axles.
I spent years building desert buggies and Baja Bugs. Light weight is key to those cars, but traction is minimal. They do not have the weight to hold the wheels on the ground. They exist on speed and momentum. That can be hazardous on a crowded forest road, as I discovered many times!.
Most of the 4X4's on the market are too light and are responsible for the rutting on our forest roads due to lack of traction and wheel spin. Trucks (and desert buggies) without weight and traction cause most of the damage to our forest roads. They may get better fuel mileage on the highway, but they waste energy by spinning the wheels when the surface is less than perfect. This includes rainy days and snow as well as off-road.
I recently took my locked 80 up to a high altitude in ice and snow on basically street tires. In over 20 miles of slush, snow and sheets of ice, I only slipped a wheel one time. All of the energy used by my truck was applied to the road. None was wasted in wheel spin. In addition, no fuel was used to dig holes in the road or to create the "washboard" effect that is caused by trucks that lack weight and traction. No road grader needs to follow me to repair damage to the roadway.
My heavy truck may rate lower in MPG, but no waste is accepted. My LC does not spin tires, does not damage roads, (paved or not paved) and does not require a much heavier truck, using more fuel, to repair the road after I have used it. My heavier truck treads more lightly in the forest and causes less erosion and road damage because it has better traction. This is why I gave up the "off-road sports cars" in favor of slow-poke Monteros and Land Cruisers. They are made of steel, they have weight, and they do not tear up roads.
