I don't know the answer to your question, but if you e-mail the guys at Blazer (in contact us area on web site) they can surely tell you. I am supposed to get my new 2420 at the end of next week or early the week after. I have read that the cooler that comes under the leaning post with rocket launchers can only be opened about 4 inches, cause the lid hits the rocket launchers. A lot of people have gone to smaller coolers to get better access. Hope this helps.
