Thanks again everyone for taking the time to help us out!!!
We went to look at the 2015 Ventana for the third time yesterday.
So,
"FLJOE" in response to the issues you raised:
1. 303 been applied to the front every month?
The front cap looks brand new, including the Diamond Shield!
2. Have the house batteries been maintained?
There are eight of them (Interstate) and the water levels look good.
3. Have the interior a/c filters ever been removed and cleaned?
They looked new.
4. Has the whole house filter every been changed?
Haven't checked this yet.
5. Has the frig filter every been changed or just reset?
Same as #4., above.
6. Has the radiator every been cleaned?
Again, don't know; however, it looks like it has never been used! Along with the fact that we don't have any maintenance history, our biggest concern is that the coach has had such LITTLE use!
"RAS100" The tires are over 5 years old by DOT date and we have new tires in the budget for 2020. One thing the broker was able to get from the owner is that the oil and filters were changed in October, 2018 and the Oasis was serviced also. Totally agree that if we decide to pull the trigger on this coach that we will be making a visit to Gaffney in the spring and we are going to purchase a "service plan" on it...have been researching those as well.
