Sue,
Again, congrats to your daughter, that must have been a great day for her. Regarding the tire pressure issue, you'll see on my signature that we have a tire pressure monitor system. The transmitters replace the valve cap and you can get as many as 16 on the RV version. The monitor itself plugs in to a 12V outlet on the dash and can show you which tire is loosing air. It also can track you trailer tires. We got ours at
www.rvcams.com. (Be careful, the website without the S in it is something altogether different!) The monitor with 8 transmitters was just over $500, each additional transmitter is about $50. We went to this system after having several blow-outs on our TT and not knowing it until another driver pointed it out. We felt it was well worth the investment.
