Hey jtdt,
I do all my cooking in the Webber Q ! A microwave can't be that difficult to work. Is the power cord plugged in? I tried to google the user manual, but the internet has never heard of a Sphere MW. Perhaps the MV thinks it's a mixmaster instead.
I'm paranoid about water leaks. Flooded the floor in my Avan first time out, and never plugged the mains hose in again! I will want the dealer to demonstrate there is no water leaks before paing any money. If they won't agree to that it's goodbye. There is no excuse for any leaks in any van. The John Gest fittings are bullet proof if installed correctly. Most leaks are from hurried installation and just require a simple push or tightening of a fitting. I'll be checking that o ring on mine.
I didn't option a dealer antenna, I prefer to use an external one on the draw bar. One less hole in the roof (to leak).
Never had much success with tuning the bloody TV anyway. After a few reds (too many) at dinner, I normally go to bed and crash by 8:00pm.
Your issues are minor. The dealer will replace the MV and fix the faulty connection on the antenna, then all is well. I've heard of a lot worse than you and (me) will experience. I don't believe any dealer spends enough time on checking the van during predelivery, they expect the owner to find all the faults, then get them fixed at the first Free service. A bit like the auto industry did 20 years ago!
I have my fingers crossed, next Tuesday will be interesting.
Cheers, Ianoz
