I've got a AWD for sale and it's been an amazing little lorry! I show jump every weekend travelling to Wales and Yorkshire in the height of winter and has done us well.
Just watched your video (: Really nice horse and forward going, i've read through your post and do you have a bubble gag on? As to make this work properly a flash strap on the top ring (the ring the cheek pieces go on) would mean you could ride less on your hands, also maybe putting her in a bit...
