It climbs a 3" curve, but even with a ramp it sort of crashes over the top like a WWI tank without a suspension. Is there a way to get it over the curbs with less drama? This can be especially dramatic with a heavy attachment sitting on the nose. P.S. Is there a good way to get the tracks clean before running on pavement? Even water doesn't seem a good way to clean them, soaking the ground where the Dingo is before the tracks get clean.
