I change the oil in our v10. It is too easy and when I get the oil on sale it is under $40.00. No need for a lift since the MH is high enough get under I also installed a quick valve which I simply sitch over to empty the oil. No driving, waiting or overpaying.
I replaced our Michelin because of terrible sidewall cracking. I would up with Firestone Transforse RT. 2 years old and like them better than Michelin for sure for a third of the price. What is with Michelin side wall cracking? This has been a problem for years.
