BE AWARE that the transparent window that the plug fits into is kind of a unique size for MCI's.  It took a lot of looking to find a pair when I broke one taking the old hardened plug out of the hub cover on my MC-5C.  After a lot of looking I found a part number, then after a lot of calling I found two (only two!) units on a shelf in a truck store in Detroit, they would not ship and I had to call my sister to go get them.  In the odd coincidence dept. I called her, and explained my issue and gave her the address, she said she drove past that store twice a day on her way to work...

Anyway, be careful with the plug and don't break the plastic bit it goes into.

As with all things electric, start with power.  I'm getting a new heat pump installed in my house, and it has a 20 amp fused supply (it's a 1 ton unit).  So if I wanted to use a transformer to run it, I would look at compressor draw being less than 20 amps at 240 volts, so 4800 watts, and starting loads of less than 3 times that, so I might buy a 10 KVA transformer.  Now I might look at available supply.  I have a 30 amp generator, and my typical plug in at home or campsite is also fused at 30 amps.  That's 3600 watts, and it will transform into 3600 watts less a bit for efficiency at 240 volts, so that is 15 amps at 240.  I still might look at the 10KVA unit, or I might downsize a bit to 6500 or 5000 KVA.  You want the whole thing to have quite a lot of headroom so you minimize voltage sag when the compressor motor is starting, although selecting a modern Mini-split with inverter driven and variable speed motors will really lower the power requirements.

As with everything, you get what you pay for.  A nice thing to have is a regulated or protected output, you can get ones that can boost low campground voltage or that have surge protection and output breakers.  At the size you would be looking at they don't have outlet plugs but need to be hardwired on the supply and output side into distribution boxes.

Example of a unit that would probably be typical is here:  http://www.220-electronics.com/10-000-watt-diamond-series-voltage-transformer-with-regulator.html

This step up and step down transformer thing is done all the time.  I'm looking at a step down transformer right now that steps around 7K volts single phase to center-tapped 240 volt, it's bolted to a pole on the street outside my house.  Typical transformers, if they are dry (some are full of oil) are massively reliable.  You open up a 60 year old piece of electronics and you don't even worry if the transformers still work.  The tubes, the capacitors, the resistors can all be toast, but you are going to have voltage!

Fresh plugs are available at the parts jobber near you.

Take one with you as a sample.

Fresh plugs on an old wheel end communicates a potentially positive message about underlying preventive maintenance to those who have an enforcement style eye...

happy coaching!

Every build, every decision, is a compromise, biased towards the builder's particular wants, needs or delusions?

The transformers are intriguing. Whether powering a mini-split, or other 240 volt appliance, such as an electric drier, electric cooking units, etc...

keeping the generator wired for 120 (another set of reasons), and the ability to make 240 at a 120 campsite is a whole 'nuther set of fascinating variables for the busnut theorist to ponder?

If thinking was money, we'd all be rich!!!

We need more typing about the selection and use of transformers!

happy coaching!

I cannot get my local O'Riley's to order it even with the SKU number

My bus is set-up with 12/24 and 120 systems; Trace 4024 and Honda EV6010. I went with mini-split 24,000 btu compressor, 9,000 btu in the bedroom, 12,000 btu in the kitchen/living room and 18,000 btu over the driver. I run it off a 5,000 watt 120/240 transformer on the road and camping where 50 amp isn't available and switch it to a 240 circuit where 50 amp is available. No problems in 4 years.

Thanks for the info.  My manual seems deficient on this subject, although it looks like it is saying to use a GL2 lube.  Mine does not have a small drain plug that I can see-- just the larger end plug itself, which is probably a bit dried out.

Roof warts do look bad-but show me a $2 million band bus with anything but 5 roof tops. You can't because they need the storage space, the roof tops are easily replaced and now most high end buses have roof liners (fences) around the perimeter where you don't see the A/C's
