2019 Tundra information needed

Hello All,

First let me thank the members of this forum for providing me with information. I have just now made an account so I can ask my questions directly to persons who have already been helpful.

I do have a few questions.
1. I did purchase the extended warranty but everyone here seems to frown on that.. why?
2. does anyone have a complete maintenance schedule. I am hearing about something about replacing differential fluid.
3. there is one dealer here who is talking about me buying some sort of paint coating because Toyota paint is bad.. OptiPlex + I think he called it? so it is around $500 think itsi am now in worth it?
4. I am now in the rust belt. Should I pay to have some sort of sealant put on the undercarriage?

You can shop around and get one cheaper. Not everyone hates them, just the cost. I paid for mine through the dealer but I have less time and more money so thats what I did and I am happy with it

2. does anyone have a complete maintenance schedule. I am hearing about something about replacing differential fluid.
I am pretty sure this is in your manual

3. there is one dealer here who is talking about me buying some sort of paint coating because Toyota paint is bad.. OptiPlex + I think he called it? so it is around $500 think itsi am now in worth it?

Dont bother. Look in the detailing forum
4. I am now in the rust belt. Should I pay to have some sort of sealant put on the undercarriage?
I never have but only keep mine for about 7 years
