09 SuperNova 6400 engine/system upgrades?

[CBerg3]

Hey all!! I’ll try not to make this too long-

We recently got a new to us 2009 supernova 6400. These forums have been so helpful!
We drove it from Texas to Maryland the last 2 months, and unfortunately had to use 2 tow trucks along the way- but found out it was the wiring plug to the ECM, (after we had a new ECM and FICM put In, and then it happened again)

We REALLY love this model for our family- we have searched for a year for this sleeping/bathroom configuration, in a diesel, and we want it to work, but my husband is uneasy after the breakdowns and it took us being stuck with no real answers.

We would love to do upgrades on the engine/ system to make it more reliable as we want to take it out for 6 plus months. We were hoping for any advice from the owners on here that have had it for a while, and that have learned from experience- are there basic things that we can do to upgrade it that may have had problems in the past or certain things that we need to be checking regularly that are unique to this rig?

I know that’s a very big question so we’re just looking for tips after reading so much online about these engines and systems. It sounds like that they can have some problems if you don’t get a few things upgraded, but we wanted to ask our friends here with the same rig as us before we move forward!!

THANK YOU!!

Welcome to the forum. You might want to post this over at the Class C forum. You'll get a lot more traction there especially if folks are 'following' that sub for stuff like this. Let me know if

Good luck and enjoy the ride. She's pretty. It'll take a minute to work out the kinks, especially if it has been sitting for awhile before you bought it. It will settle out.

Thank you! I will try and figure out how to do that- we would love all the help and input!

Hello CBerg3,

I have a 2012 Supernova 6400 and it has been good to me and my family. There are a couple of things that do tend to cause problems withe the International 4200 chassis. Most of the issues can be found on this site. As mentioned above I would search the Super C section for “Supernova” and you should get a good list of posts/things to check.
