Well, I already have the 1527 ordered and they are making it for me so I don't think I can turn back now. My truck is most likely going to be heavier than his so maybe it'll be able to handle the power better. I can also have the slipper set a bit looser than super tight (so just tight). If it ends up being too much to handle, I can order a 1521... but hopefully it won'tbe!
