16 with g2 can I drive a company vehicle?

I'm currently 16 with my g2 license in Ontario. My grandfather owns a business and has a couple trucks (2005 Ford F-350 and a 2006 dodge Dakota) I was wondering if I could borrow one of them for the weekend and be covered and everything. I also am on my mothers insurance as a occasional driver if that helps.

2003 Ford F-250 Powerstroke won't Crank, won't start?

When I turn the key, I get a rapid clicking noise, and the indicator lights on the dash flicker. Glow plugs also sound like their barely getting enough juice. No crank at all.

I hooked up my 100w solar panel with a automatic12/24 volt charge controller, which said batteries had a good charge. Went ahead and charged them fully, followed by cleaning the post, and battery connections of corrosion.

Result was the same, won't start.

Any ideas what could be wrong?

Should I buy a 7.3L Ford F-250?

I'm 15, and I'm looking for a 7.3L Powerstroke. I want a 1994-1997, but will take a 1998-2002 if I find a deal that I like. Mainly, the older body because I can find them cheaper and I actually like the square body. I want to start looking now even though I still have another year before I start driving because I have enough money to buy one ($8,000-ish) (which means more left-over money for new parts), to start saving up money for parts I'll need (to know how much I'll need to work to get all of that money before I start driving), and some relatives could sometimes use an extra car/ truck in my family/ my family could use it.

I want a Diesel because I can get better fuel mileage, and boy do I want to stick an MBRP with a straight pipe on it. I'd like to keep the truck that I buy for decades (probably about two or three) before I have to upgrade, as I don't think I'll want a new car a lot. Plus, I will occasionally haul a 8,000 pound camper, and regularly in the Summer haul a light-weight landscaping trailer.

But, should I get one?

(I should mention that I have a steady, minimum wage income as a teen, and a mother who would keep my truck on the road for anything)

Yesterday I accidentally filled my gas engine Ford F250?

Yesterday I accidentally filled my gas engine Ford F250 with diesel and wasn't able to take it to a mechanic due to it being late in the evening. I do plan on having it towed first thing this morning as soon as the mechanic shop open. How much damage can be done from having the truck sit overnight with diesel in it?

Throwout bearing or heat shield?

I have a 2006 Ford F250 super duty kingcab 6.0 with 6 speed manual transmission. It just started making a clattering sound when i let off the gas in 1, 2, 3 gear but not in 4, OD or in Neutral with or without clutch engaged. Could this be throw out bearing or heat shield?

Do I have to manually lock my Ford F-250 4x4 hubs?

I just bought a 2005 Ford F-250 King ranch. And this morning the grass was really wet and my back tires were spinning. So I put it in 4x4. And the 4x4 light came up on the dash. But the back tires were still spinning. So I just pulled forward and got a runny go in reverse and got out. Maybe I just didn't push the gas enough for the 4x4 to lock in? (I didn't wanna mess my grass up even worse and j was late for work). Or is it something with the hub locks? The writing is worn off so i don't know what they're in. Or what they say. How do the hub locks work? I know there's either a "lock & a free" or a "lock & a auto". What's the difference? And what do they need to be in full time and so I can just hit the switch and be in 4x4? Please explain!
