whats the difference between a muggy and truggy?

[blueb8llz]

first off...what is a muggy and a truggy? from what it seems, it sounds to be like a stadium truck but usually in nitro and 4wd...am i correct?
a truggy or muggy sounds exactly like something im looking for. ive owned all types of rc cars and now i want something in between a monster truck and a buggy. so i thought a stadium truck suited me the best, but it lacked the 4wd. and i missed the bigger tires and ground clearance from the monster truck. so ive stayed with the monster truck for a while, but now i want something that handles better....truggy ..muggy? can somebody tell me a lil about those?

thanks
