I am having difficulty finding an insurance company who will provide Comprehensive Liability or Full Coverage on my 1984 Nissan MIrage for the value of $$ that I have put into it for renovation. I am wanting comprehensive in case of theft. Does anyone know of an insurance company that provides this kind of coverage. Also, information on how to make an RV more secure to prevent theft. Unfortunately, I am not able to park my RV in a more secure area like a garage or fenced in yard.

I recently purchased a 1984 Nissan Mirage and would like any information on the Mirage that was also manufactured by Toyota. I am looking for an owners manual and/or information on where I can order parts for the RV. I need to replace the thermostat on the propane heater, and the water pump is also broken. I would appreciate any information or help as I intend to renovate this Mirage as a ongoing project. Also, I am having difficulty finding an auto insurance company who will provide full coverage on the RV due to the age of the model.
