God temporarily dwelling in the tabernacle did not make the tabernacle God, any more than the Holy Spirit dwelling in Christians makes them God. That God is present everywhere (called his "immanence") is not proof of the Trinity--God in three Persons (there are other biblical proofs for that)-- but it does explain the omniscience which only God possesses.
Love the discussion! I agree the Tabernacle was the place to connect with GOD - and in fact was only accessible by the HIGH Priest (the innermost part / Holy of Holies where the ARC of the covenant rested). The VEIL between that separated the Holy place where the high priest would do all the “things” required before entry into the Holy of Holies was torn from TOP to BOTTOM the moment Jesus said “It is Finished” the final sin offering was ACCEPTED and it was no longer necessary for the High Priest to perform sin offerings before entering into the presence of God ! Amen !
