Big monster truck

My 3 year old son asked for a really big monster truck for Christmas. But I don't want to spend. too much on a truck he will break on a few weeks.Does anyone have any suggestions on a large, rugged truck for $100 or less that a 3 year old would like

Like how big of a truck? My DS is obsessed w mud trucks right now lol

I don't know probably a foot tall at least. It depends on what we can afford. I just want him to be impressed by it
