Just some test comments :
Inflated a 4.20 mtr sib inside a shadowed garage to 3.5 psi gauge metered at an altitude of 2,350 mtr above sea level, the sib was placed on a flat bunk trailler well strapped & covered and driven to the coast.
Arrived completely defleted to 1.0 psi with hanging straps over sides, had to be pumped to full working pressure again at sea. What you must NEVER DO is transport any well inflated sib/rib from sea level to high altitudes, deflete at least to match same pressure when arrived down and strap loose, release straps tightness at least twice on your way up, or you will be extremely overtighting the tubes.
If you do not have a gauge, better is to inflate boat once arrived to your boating location or you wll hear a load bang on it's way up
No problem going down from high altitude to sea level 
Happy Boating
