Just to put things into perspective here, let's say you are about 150 lbs. and you are able to pull a wagon weighing up to 75 lbs., You know you can pull the 75 lbs. you have done it 100 times before, but you are still going to feel your body temp. rise and possibley even sweat due to the fact that you're pulling that extra 75 lbs. rather than walking your average pace. The human body wasn't made to pull things at a constant daily rate. The same holds true for your truck. It is made to handle the load when needed, but you are putting more wear and tear on the engine causing the temp to rise slightly because it is having to work harder than it was originally engineered for. If the truck were meant for constant hauling, it would have a Caterpillar engine or something engineered to handle a heavier load on a daily basis. But depending on the truck you are towing wiht, the engine may not be rated for the same weight as the suspension under it. Also the type of fuel your are burning makes a big difference, if it is gasoline, it will burn hotter regardless, but if it's diesel, they are made to handle slightly higher tempuratures.
The sun is one factor that causes the atmosphere to get hotter.
Yes, the heat rises to the top of the engine.
It's dependant on what you want. If you live in a hotter climate, select a lower temperature thermostat; that causes the thermostat to open sooner, keeping the engine a little cooler... hopefully. If you live in a climate that is either normally cooler or seasonably cooler, a hotter thermostat can help the heater work better. A hotter thermostat has been demonstrated to be SLIGHTLY (almost insignificantly) at helping the engine run more efficietly.
The vehicle does not have any airflow across either the engine or the radiator to cool things down like occurs when driving, if at an idle. This, coupled with a diminished flow of coolant through the engine at idle speed creates undissipated heat.

Because if you have a black vehicle or even just a dark vehicle, it can be hotter than a vehicle that is a light colour such as white or gold. Darker colours tend to absorb more heat.
all things equal both are the same..In air cooled engine the diesel is slightly hotter.
Vehicle manufacturers recommend a 50/50 mixture of antifreeze/water in the cooling system all year round. The antifreeze helps the engine run cooler in hotter weather and prevents freezing in colder weather.
The letter 48.
A Thermostat enables the engine coolant to heat up quicker. One of the advantages is that the vehicle heater will get hotter faster. When the temprature of the engine reaches about 92 degrees f the thermostat opens to allow the engine coolant to circulate to the radiator which maintains a safe temprature for the engine to run at. A vehicle will run without a thermostat fitted. But it is not recommended on some engines as it may cause a hot spot which could cause the head gasket to blow. A typical example being the Leyland O series engines from the 1970s
