The second owner did diddley squat as far as keeping any records, as to what (if anything) was done from that point on. I purchased the unit in March 2017.
My local mechanic suggested that I need to do the following, before I make any long adventures, since there are no updated records.
1)- Radiator and oil cooler flush
2)- Air conditioner pumped out, cleaned, leak checked and recharged
3)- Check brake pads, rotors, etc. and flush brake system
4)- Transmission flush
5)- Inspect rear differential
6)- Inspect/Change spark plugs (leave alone)
7)- Full service on Onboard generator (yes)
8)- Oil/ filter change
I apologize for the long list, but need y'all ( the experts ), for your input and it would be greatly appreciated.
I agree on everything on the list except not too sure on item #2 & #4.
Have only driven her about 400 miles and have not had any problems with air or transmission.
Thanks to all of you veteran RV'ers for any and all comments.
• Because of condensation that gets into ALL fluids and lines (especially if you live in a humid climate) and then adding to the fact that you have—no baseline
—to go by of when all the fluids have been changed last, that was my 1st priority on our MH and should be yours too. So that means thoroughly flushing and replace all fluids
: coolant (be sure to use the right replacement coolant - check manual for that year), brakes, power steering, engine oil (be sure to used OEM recommended filter type), tranny and differential. While they are changing the diff oil have them check and be sure the diff vent hose is clear and working properly. I would have this all done at reputable shop that has all the proper flushing equipment to ensure a thorough job. I'm particularly anal when it comes to maintenance so I also had my fuel injectors cleaned and flushed and then I maintain them by adding BG Products 44K to my gas tank at every oil change or about every 4K - 5K miles.
• Another step you can take on your radiator is go to Walmart and buy a gallon of Simple Green, pour into a pump action garden sprayer and saturate your radiator, oil cooler etc as much as possible by opening your hood and getting it in there. Let sit for about 15-30 minutes, hose off thoroughly with a hose
• Then check DOT date of all your tires on the sidewall. If more than 5 years old have them inspected and for sure watch your PSI based on your MH weight. Don't know the weight, get it weighed. A lot more can be said here about maintaining tires but you can search here for that info
• Grease the front chassis
• Leave spark plugs & coils alone
• On the A/C units - don't do what he recommended but do read this
• Get on a crawler, get under the chassis and look at ALL rubber hoses throughout the chassis and anything else rubber for that matter. More than likely they are hard and/or dried out. If they are cracking, replace them. If just dried out use this product to restore moisture and elasticity. This stuff is quite amazing:
• While you're under the chassis, Tejay, a fella here on this forum brought up an excellent post that every FORD chassis owner needs to check. You can read it here. Read post #4
• Check battery water levels and also perform an Electrolyte level test using a hydrometer (also at Walmart for about $4) Batteries always seem to give people grief so knowing where you are in this dept. also will be good. Here's just one link that kinda explains this test a little more

• Go to manufacturers website, type in VIN# and search for any recalls or service bulletins and then check your MH to see if they have be done. If they we're, they were probably done by the 1st owner during those 1st years.
• Sanitize fresh water tanks
• Change out all smoke and carbon monoxide detector batteries. Then, your propane leak detector is probably out of date too and needs replacement. It's near the floor usually around the sink/stove area. Be sure to check expiration date. Replacement can be found on Amazon.
• Check/Replace fire extinguishers
There are so many more things that should be checked but this will get your started with the most important stuff and as you said, "what should I do first". After these things have been done, now you have a good baseline, your safety stuff is up to snuff, you can tackle the other stuff you want to check/upgrade or install bling goodies for the DW.
