John, It is a U-Joint rig, not a Sportsmobile! We have traveled the country in this beast for 8 years and have put 47k miles on it. I replaced the tires at 35k and they still had plenty of tread left… I only replaced them because of minor weather cracks. Kevin speaks the truth; the only downside to this rig is that it’s not a diesel. I wish it had a 7.3 Powerstroke in it, but I would settle for a 6.7, if I could find someone to do it right. As for the weather “one state line away”, today is supposed to be a high of 73, which would be the “chilliest” in recent memory. We’ve been in the 78-81 range down here on the Key West Navy base for the past 5 weeks. I hope to park this thing beside the Milliman barn in the near future.
