Sorry, but no that's not true (for 99% of those reading this), what paste wax do you use?
Unless you're using Collinite or a handful of "online only" specialty paste waxes that are durable, you're maybe getting 30-60 days of real protection.
Please don't say nu-finish or anything that you can get from a local walmart/advanced auto.
If you go through the effort of paste wax, just understand that there are sealants and semi-permanent sealants that take less time to apply (not including the spray and rinse coatings) which will last 6-24 months depending on your local weather conditions.
As you said, your truck, do what makes you happy. A 4runner will probably take you just over 30 minutes start to finish with a paste wax (if you are quick) that will last, optimistically, 90 days. A sealant like collinite/Mckee's will be marginally quicker to apply but last you 6-24 months. A spray and rinse sealant will take you 2 additional minutes to incorporate into a regular car wash and last you 90 days. I clay with a clay sponge which is marginally quicker than regular clay too.
This is all assuming you wash properly, and are able to avoid wash-induced swirls and marring. If you have a brand new truck and want ot keep it that way, your #1 priority is to avoid touching the paint as much as possible. The old ways of paste waxes that need buffing, bead water instead of sheeting would be a point of contact that I would recommend skipping to put off the need to machine polish the paint. (if that is your goal)
