Well up until level 22 or so I'm on foot and make about 10k in gold during that time. From 22 until I retire I'm almost always on my horse (destrier then courser).
This is my gear, and I usually lose about 20-30k in gold per gen (that's a rough estimate it really varies). But 90k gold is 10k less than I have, and most of my gens (I'm gen 6) I've had under 50k gold. My first gen was the only one I had to get off my horse when I was poor, selling looms (and still able to buy a loom for every retirement) was the only way I could make money.
My total gear loadout is usually anywhere from 50k to 60k (obviously taking into account heirloomed items say they cost more).
actualy man you are right. You don't realy need much money. I like to ride crouser,wear mail shirt,skullcap,heavy lance,and sarranid boots and i make money.
I loose it a lot,but then i get more then i lost. I totaly understand you why are you always riding and not playing on foot.
Cavalery is so awsome. I will sell my loompoint after retire so i will ride for next 2-3 gen.
It is fustrating,but it is so much fun.
Only thing i realy hate are horse archers,and crossbowmans.
Loomed items increase only total cost of your gears,but repairs are same as you have it non loomed. Because increase of it value items can brake more often,but repairs are same.
