Like they say "If you own an RV you either need to be handy or rich". Fortunately I'm pretty handy. A good example is my water pump quit working last week. (Under warranty) Called the manufacture since my buying dealer is 300 miles away and the closest is 50+ miles away. They are just sending me a new water pump for me to install. It would take me longer to hitch and drive to the nearest dealer one way than it would to install it myself. And Northwood doesn't have to pay to have a tech guy install it. We both save time and money.
It also helps having a manufacture that will work with you. Some dealers and manufacturers are very inadequate. A good example of inadequacy is on our last TT we had, the table in it had a crack. The dealer showed it to me during PDI and said they would order a new one. When the new one came in they called and said bring the TT over (5 mile drive) and we'll put the new one in. When I get there, they take me out to their warehouse and we look at it. It's the wrong color stain. Haul the TT home. Fast forward 3 weeks and they call again. New one is here. I tell them it will be a week or so before I can get there. Drag the TT over again. We go to the warehouse to look and it's the wrong style base and the top is warped because it was freezing out, which is why I told them to wait a week. They then order another one. Mind you it's costing close to $300.00 to ship theses tables from Elkhart Id. They could've given me $300.00 and I would've found one nicer for a few $100.00 more. So now they call again and the 3rd table comes in. This time I leave the TT home and just drive the truck over. We venture out to look and still the wrong table color and style. So we mix and match and I actually end up with a nicer table than before. They said keep the original one that had a hair line crack. 1/2 of these problems were Heartland sending the wrong table even with pics of the original sent with the order. The other 1/2 were the dealer not doing a PDI on the new table before calling.
I guess my point is it's just sometimes easier to pay a little extra and buy your own parts or grab a screwdriver and start turning. Doing you're own work when possible will make it easier when you have issue out on the road.
