Sure hope all starts easing up on you soon.
This is not directed at you, as either you did do this and bought the coach with the price reflecting it's condition, or you did not do this and now it's too late too
! (I'm a poor writer, so please see the grin, and understand this mostly directed to future readers that researching a coach purchase.)
One of the most important things when buying a used rig, is getting a solid understanding of the condition.
-Receipts, documentation, RECEIPTS - are king. Trust no one, RECEIPTS are very important.
-Even with receipts, unless you are a qualified experience individual, get an independent inspection of three key things:
1) Coach and house equipment (heaters, roof, slides, batteries tested, inverter tested, all AC's and Heat Pumps tested, all dash knobs and gauges functioning, leak investigation, and I'll toss generator into this category too)
2) Engine/trans. Include pulling oil and trans fluids for analysis. If a CAT, go to a CAT shop. If Cummins, yep - Cummins shop. Detroit? Of course.
3) Chassis Inspection - Included date codes from all tires (if a dealer, especially inside dual's), air bags, bushings, wheel hubs, brakes.
When buying coaches at this level and costs, sometimes spending a $500-750, and being willing to gladly walk away - is money well spent.
OP - Again, sure wish you the best ahead with your Magna. These are complex coaches, and if maintenance has been neglected, or shoddy work by others before are involved - you now have the 'opportunity' to sort these out and correct. The good thing, is usually these coaches 'foundation' warrant the time and effort and yeah, the funds, to sort things out. Once you have 'caught up' you will know the baseline of your coach. (One tip, is to possibly go in and get a full inspection of things now, and come up with a punch list of things that need to be done 'now', and other's that can be done later. Not sure what part of the country you're in, but many good honest shops can do this for you. Then you can layout a schedule and budget plan accordingly. Ask here for references to shops near where you are, I'm sure you'll get good input.)
My wife and I are in year three of our adventure with our 04 Allure, very happy with our CC choice, and feel part of the fun is in making this 'our coach'.
Travel safe, and look just ahead to when the funds stop flowing for repairs, and go towards the reason you bought the coach - travel and fun
Best to all,
