This is all good stuff guys thanks a ton. I do not however think I'm going to be able to change the oil prior to my 256 mile trek back home. This concerns me. The tires are pushing their 5 year mark if that is the life limit for RV tires. It has gotten used once a year since 2006. And I believe but am not sure was serviced at the end of each trip up until about 3 years ago. When it's caretaker changed and has been neglecting it. Barely winterized it and so on. I'm sure he hasn't changed the oil in it for the last 3 years. He also mentioned the word mice which concerns me. I'm really going to have to think of way to get that oil changed before the trek home. If I check the air pressure in the tires should I be relatively safe with those?
