I've done both the Muggy and the 8ight T and I can say that they are not alike at all.

The Muggy was a pretty nice conversion and was pretty easy to do. I did get rid of the Muggy because I already had a Monster GT conversion and liked it better.

The 8ight T is a tougher truck than the Muggy was. I bash the heck out of my 8ight and haven't broken anything significant. The 8ight would also be an eaisier conversion since Mike sells a mount.
