One of the crazy mind blowing things that I realized recently was that there was certain types of sacrifices and offerings which could be done outside of the tabernacle. "Ascending offerings and peace offerings".

Moses even gives instructions on how to build the altar in the Torah. Here's an example of Joshua building an altar even though he has a fully functional tabernacle.

“And Yehoshua built a slaughter-place to יהוה Elohim of Yisra’ĕl in Mount Ěyḇal, as Mosheh the servant of יהוה had commanded the children of Yisra’ĕl, as it is written in the Book of the Torah of Mosheh, “a slaughter-place of unhewn stones over which no man has wielded iron.” And they offered on it ascending offerings to יהוה, and slaughtered peace offerings.”
