Hi Quietly_Learning, I'm glad you're Vocally_Learning now !

Its a difficult question with many answers.
It sounds like you would really need to re-evaluate everything in your “heavy kit” and prioritize, depending on circumstances.

What items are essential to life ?
Which will defiantly be used (given what you “know” of the situation) ?
Which “might” be used if circumstance X occurred and how likely is that ?
Which are unlikely to be useful ?

If you are out and about, (or at home), you can cache equipment and retrieve it later;
if you have expensive or dangerous items which you are going to cache, you may wish to take special precautions when leaving them.

Basically yoiu need to re-evaluate and prioritize
