I have a 5 year old pack llama fully trained for sale. He is a gelding and halters, leads, and trailers. This year he did several longer hikes including a 12-mile day with 50 lbs and a 4 day 31 mile trip in the Eagle Caps. he does have weak pasterns so it is unlikely he will ever be a super heavy packer but manages 40-50lb loads just fine. He is IRLA registered. Would also consider including his pack and panniers, flaming star set up. He is 45" tall and weighs just over 300lbs
