things to look for when purchasing a 2007 seneca 35gs July 14, 2020, 03:35:09 pm im new to the group but have been reading the posts for days, as well as new to the large diesel MH game. im looking at purchasing a used jayco 2007 seneca 35gs with 35000 miles on it. what do i need to look for when doing my pre purchase inspection? what are the glaring issues i need to be aware of while performing driving tests and gen tests. what is the proper startup procedure to check all the appliances and electrical equipment? basically want to know what im getting into possibly as well as what to look for onsite. any help will go leaps and bounds at inspection time. im a very well educated shade tree mechanic but not a veteran at this by any means. thanks again everyone.
