It works! This is great news for me as I have spent the last day or so looking for a new portable grill to replace my SJP. The SJP is just not big enough to feed my family+inlaws, which is where we typically travel to.
Thanks for the response Phil. I checked out your concerns.
1. The legs lift the grill up high enough that it doesn't sit on the drip tray.
2. I don't think the grill has to be lifted up any higher, as there is a little space below the drip tray and several inches between the drip tray and the bottom of the grill.
3. Weight is not any worse than the SJP with ash and leftover charcoal in it.
4. The lid is a bit of a concern. It's not heavy enough to topple the grill, but if you fling it open, it does cause the grill to shake alot. If opened more deliberately, it won't cause any problems.
5. Other issues: The drip tray would need to cleaned out before placing the grill in your car. Also, the whole thing needs to be cleaner than general for it to transported cleanly. Lastly, transporting this thing requires taking the massive tank with you. Is there an adapter you can get to convert it to run off of one or two little tanks.
Overall, this thing is great. Having looked around extensively there is no other portable grill this large (ie: no other grill that can fit in your trunk, and that also has about 400 inches of grilling area, and that can cook indirect nicely).
