I've painted, updated outlets, lighting/ceiling fans so far.

Many investors make good money, but they are miserable.There are several serious assets a person should have before they jump into real estate investing such as:a) enough cash to handle the unexpected repairs, vacancies, tenants who don't pay rent and legal costs,b) enough math skills and many other experiences about properties to understand whether or not the purchase of a property will result in a profit,c) enough math skills to calculate your profit at the end of every year and this includes understanding enough math to calculate your profits from depreciation, rent income, rent increases, property appreciation and increased property value that results from rent increases e.g. using the Gross Multiplier.d) the mental maturity and skills it takes to deal with tenants who, who destroy your property, don't pay their rent and then to deal with evictions and attorneys without getting stressed and going insane.e) be knowledgeable about real estate rent laws andf) ability to produce accurate bookkeeping records for banks annual audit and the IRS audits.So, when many people ask if the real estate business is good to get into I don't think it is right to just tell people, "'Anyone Can Do It".

Although the terms of the unexpected new lease are not ideal, that was not the deal breaker.

Other simple things include grounding/reversed polarity of outlets (you can buy an outlet tester at Home Depot for $5), using foil-faced tape at furnace & water heater flue pipe connections, operable smoke/CO detectors, cracked/chipping/peeling paint if your applicant has children under the age of 6 (I think?)

Usually unexpected repairs.

. - over last 2 months property manager has made about $750 extra payment while I have lost about $2000 unexpected losses and it’s all a result of the property managers decisions.

Put some unexpected repairs into your budget and get as much information from the existing tenants and the home inspector.

You need a 30 or 50 amp outlet depending on size of the camper and appliances. 

They’re already wired for cable, have grounded outlets, and gfci  everywhere.

@Supada L.Yes, burdensome unexpected costs are part of REI, but I'm curious about the inspection reports dating from last year that you mentioned.
