I have a 2003 Dodge Grand Caravan 3.8 V6 with a complete Braun Mobility package including hydraulic that lowers the van's right side and auto opens the side door unfolding a ramp. I also have a locking chair system installed on the passenger side so the mobility chair can drive up and lock into the position. 

I just had my air serviced and the shop told me I needed either a new van or a new engine. I'm just looking for advice on what to do.  My wife has ALS, " Lou Gehrig's Disease " and the Mobility Van is a necessity. Due to the COVID-19, my credit is tanked and I am having to file a chapter 7 bankruptcy, which makes purchasing a new van out of the question. 

Should I try to find a rebuilt engine or find a good mechanic who can rebuild the engine in the Van. The current engine has about 145K miles. Any suggestions are much appreciated.
