What is Reddit's opinion of dbest products Trolley Dolly, Blue Foldable Shopping cart for Groceries with Wheels and Removable Bag and Rolling Personal Handtruck, Standard?

From 3.5 billion Reddit comments

I have a decent sized office with plenty of storage and this is what I keep in it:

• a case of water
• some canned goods, dry goods (instant oats) plus some snacks
• emergency blankets
• first aid stuff
• candles
• battery fans and a battery pack
• extra toiletries
• baby wipes
• extra meds
• we also have a shower room here so I keep towels and extra clothes in a locker.
• emergency solar/crank radio

If I got snowed in, I figure I could shut my office door and stay comfortable-ish for a while.

I also carry a 65L hiking pack in my vehicle (I know you said you don't drive but maybe you could have a look at the Ultralight hiking group? I'm sure you could get plenty of ideas for a fairly small lightweight bag). I have everything I need in my hiking pack to walk home. Tent/sleeping bag & pad/food/water filtration/Jetboil/etc. I hope I never have to but I could.

If you're worried about weight, you could always get some sort of cart like this.

Did a bit of searching. This looks like it might come close to what you're looking for.
