Wow! You sure have had your issues asherkobin! Excellent coverage of your issues.. thanks for posting!
Kate and I just returned from our own maiden 'voyage' and have had only a few issue. Overall we were very please! I do agree with many of your design problems... so here we go...
1. Our furnace works well... the whole issue like you mentioned is the thermostat in the bathroom. Silly!!! I pulled off the thermostat cover and noticed two things that can be adjusted... forgot to take a photo... but I believe this will fix the ridiculously long on/off cycle. We had to prop the bathroom door open a bit so that the bathroom area temperature was more in line with the actual cabin temperature.
2. All our drawers seem to be fine.
3. the door hook on the lower curved cabinette broke the very first day we took our Bambi out! It is a horrible design that we will probably replace with something else rather than get it fixed.
4. our subwoofer works (maybe check your fuse panel), but has an annoying low frequency noise (not an ac hum) that is rather annoying.
5. our stereo housing is ok... true not especially built well but seems fine. we have no vibration from it. I'd gather that the design for the stereo inside the cabinette was more for esthetics.
6. luckily no leaks!
7. faucet fine
8. status monitor works well.. but its annoying having to toggle and wait for it to cycle through everything, just so I can check the battery level...
9. the bed extension flat surface is getting scratched by some nail or something that is not accessible... not a big deal I guess.
10. countertop trims seem fine.
Our own comments from 7 nights usage...
Overall we found the 75th to be a delight! Nearly perfect design and function for our needs!
One of our favorite amenities is the shower! Flick the heater button and in less than 5 minutes you have hot water awaiting!
The fridge worked well and drinks/good were good and cold. The freezer temperature was great as well for ice making.
We found for the 2 of us, more than sufficient storage! We actually had a few areas that we haven't even used... but no doubt will fill in time
We loved the position and design of the windows. We missed out on the vista view windows, but really we are happy
The TV can be viewed from either the dinnette or the bed.
Not so good...
#1 would be the thermostat in the bathroom of all places and the super long cycle. Currently we are forced to manually control the heater or face cold/super hot cycles.
Subwoofer noise is really annoying.
That cheap plastic curved door hook is useless.
Whenever we used the stove we had to take the fire alarm by the vent ceiling down or it would set off.
We kind of wished the door porthole was clear so we could see out of it. Not sure why it is frosted... maybe to match the bathroom porthole?
Watch out for the window handles by the bed window! Kate almost poked her eye out on one of them that I had open and unlatched outwards.
A mattress topper (not foam) works well to make the bed more comfortable.
Wish they had built in an inverter for those of us with no hookups... even switchable, especially for tv watching. I have one that we used, so no big deal I suppose.
Don't put anything close to the propane detector. It will be blocked and will set off. It is VERY loud!
We will be camping mainly in state parks with no hookups. As such, I spent the week monitoring our power usage and recharging when necessary.
Over the span of 7 days we had some difficulty keeping the batteries topped up to meet our demands. We have a Honda 1000 which worked well, and is very quiet, however the Bambi's Parallax converter/charger just doesn't do a bulk charge at a high enough current, so we had to run the generator for about 4 hours a day.
Our power usage consisted of using minimal lighting... never more than 1 or 2 lights on for on average 1-3 hours per evening. We used the water pump to wash a few dishes once or twice a day and for each of us to have a shower each day. We used an inverter to power the TV and watched maybe 1 hour of tv or a DVD most nights. We used the heater 2 nights. Once with on/off cycles through the night, once getting up several times during the night to turn it on/off. The heater fan is a major source of power draw, especially considering it is on for longer periods of time (see Camp ADK - 40 Winker - Electrical
). The fridge also is probably a big contributor also since the fan is on a lot throughout the day and night.
We had to fill/top up fresh water every 2 days on average. We emptied the gray water into a 22 gal tote and pulled over to the dumping station every 2 days. We did not scrimp on water usage for the shower since we didn't mind taking the tote down the road every 2 days. Having real navy showers could have reduced that to once every 4 days. We have not used the black water system yet
Conclusion - summer time battery usage should be less as the heater will not be used. Upgrading batteries and/or using a smarter charger like an Progressive Dynamics PD9245C, 3 stage charger may make topping up the batteries more efficient.
I'll be posting a more detailed report with photos on our 40 Winker site in the near future.
