I agree... there are negatives but don't let them get you down.
We have liked our 31L so far. Still consider it the best model for us of those that i have seen. I have always said it doesn't look like much on paper, but the simple floor plan works well.
The TV is in a good location
lots of counter space
good long sofa (I wish we had the jackknife instead of the air mattress though)
DW likes that the bedroom is separated from the living space a bit.
I didn't like that the shower was not in the bathroom, but it actually isn't a bad layout at all.
Our toilet is up on a platform (tank under), and I didn't realize it until the 1st night, that it's too high.... I'm 5-10 and my feet don't touch the floor! Not a show stopper for weekend use, but not ideal.
The grey tank is too small in my opinion. 5 showers (4 girls w/ longish hair), even trying to conserve with navy showers, fills it up. I replaced the head with an oxygenics but haven't had a chance to see if that makes a difference.
Ended up replacing the accordian room divider at the bedroom with a curtain.... much better.
Keep an eye on your exterior lights. Unless they changed it for '16, they use a bad design for the tail lights. I recommend retightening periodically as the foam gasket compresses.... and when you see signs of moisture inside, open up to dry immediately.
Seems that the marker clearance lights also get moisture in them, but they don't seem to cause as much problem.
The drawer slides in the bedroom were not installed well.... 1 screw where 3 would have done nicely.... and they didn't support drawer filled with clothes (nothing heavy). I changed them out with heavier slides form lowe's
I found tons of little things.... loose screws and the like.... but nothing else major that comes to mind....
I made up a checklist
used a few from here as a basis
I found most to be too long and complex, so i simplified
Stuff to bring
ac outlet tester
Things to check
Battery - test with tester
battery charging on shore power
battery charging on genny
Water heater function
Water Heater Drain
All faucets hot and cold
Warranty Docs for appliances
Basically, I crawled under, over, through, and around everything..... including the roof and undercarriage
I filled up every tank and drained them
I used every system
turned on every tv
turned everything on, in every combination.
I think the dealer plans for something like an hour for the PDI, I took maybe 4 or 5, and still missed stuff.
I suggest scheduling the PDI for early in the day, not afternoon
and plan it early in the week, not friday or saturday in case the factory needs to be called.
make them address every issue before you finalize the paper
plan to stay in it the first night at a campground nearby, or at the dealer's lot would be even better
have a standing appointment in the service bay the following day to fix things you are sure to find once you start loading your stuff and using it.
PM me so I'll see it, if you ever want to discuss or brainstorm....
