Is this strong enough to be firmly secured with luggage straps to which I'd attach the seatbelt or would the sides collapse?

I have this pet carrier, it's pretty strong but I'm not sure exactly of your question and what you are wanting to do? What do you mean by luggage straps and a seatbelt?

yes, it is very sturdy. it has thick canvas. It is almost like a mini suitcase for your shoes. I think it would work well for your car traveling purpose.

The bag supports my 24 lb metal machine. The bag is suitable for car travel,not for shipping. No additional straps on the inside. A lighter machine may need to be anchored.

It should hold a good amount of weight. If the buckles are slipping(moving) out of place, check to see if you have them fastened correctly. They shouldn't move.

Yeah, and the two other straps allow u to secure it so it will not jump off. If you only have a luggage rack u will need 2 more straps. To secure it. Nelson Rigg sent me two more upon request

Yes this would work fine. It's sturdy and stayed in place with the seatbelt for us across country.

Yes, the straps are wide as well so you wouldn't have to worry about them being weak and coming undone.

Yes it likely to buckle a little, I tried tightening it a little and it still is a little wobbly. You did not mention in that iu your description of the product. It wobbles a little when you put it togther. I think it might work but I am not sure if its worth the price it was sold for.

The hook and bungee work great for me. I use to secure my luggage on my motorcycle for weekend trips. Longest was to Vegas and back with no issues. The weight they secure is maybe 20 lbs at the most and I use 4 straps to do this. The main reason I git these was the ability to adjust the length.

I doubt it. I don't think the side braces would be strong enough to hold a seat and even moderate sized person. I don't see any other place to fasten a seat.

I use it w/ my 17" laptop & yes, it is safe & secure...no bouncing. it sits firmly. Hope this answer helps.

it closes with velcro i did not have a problem in afixing it to the seatbelt. you can raise it up or down to fit your comfortzone.

Yes. The provided straps are secured through rings on the bag. I had no issues with just the side racks.

You have both options with this one. I use the anchors, which I think are the best way to secure it if you have the anchors installed in your car. I didn't try the seatbelt attachment to the base though.

Yes, but carefully. The straps are wide but it will wobble if you're not careful.

It doesn't totally collapse, but I used it for a rolling carry on and then once I got on the ship used it as a cooler

The stability and any sharp edges would be my main concern. Another factor is what you're hoisting and the danger of injury if something fails. The strap has a 10,000 lbs breaking strength but a torn strap would be my fear.
