Halachically, why would a person need a succah if their on a Chol HaMoed trip, at work, or on the highway? The halacha is, “Teishvu K’ein TeDuru”- you must live in the succa as you would live in your house. So if I go on a trip to an amusement park, and I am no longer at home, I don’t shlep my house with me! So I should be potur from eating in a succa whenever I am not home! What’s pshat in a pop-up succa?? Can someone clarify this issue, am I mistaken?
