Hi.
.......................................................................................................
Masao was running away from his uncle, Teruo Sato, who was trying to kill Masao.
He was a fugitive from his uncle.
Finally he reached Los Angeles, California, to see his friend, Kunio Hidaka.

(Quote)
He bought another pair of shorts and jeans and a tee-shirt and a handkerchief and socks, but he left his old clothes in the dressing room of the store. He was carrying enough of a burden.

(from THE CHASE by Sidney Sheldon)
.......................................................................................................

I'm not sure about the meaning of the last sentence.

"A burden" is not a material, but his mental pressure. He had just the new clothes he wore, and he had to be as light as possible. He had to be ready to run away from his uncle's men and from police.

Is my interpretation of the sentence correct?
Thank you.
