jjdcamper's frustration with his Aframe is understandable. He had major problems with the Formica top and his dealer has just basically put him off. Summer is slipping away while the wheels of progress for correcting the issue seem to be grinding to a stop.
After that, every odd "not right" thing, be it large or small, becomes a glaring reminder of the original big issue. Each of those items get put on the growing list of frustration...do I fix it myself or will that void warranty?
Then there are some folks don't have $10K to lay out all at once, so they must take out a loan. That payment is a monthly "slap in the face" reminder of the collective problems.
And so the frustration grows....but enough of what you can't change or fix...
Instead, let's try and resolve some things on the list that won't void warranty. I understand that the consumer shouldn't have to deal with it, but addressing a few items oneself will offer hands on experience. Pride in ownership, as it were, bull by the horns and all that...
When you get your camper home, let's try to first resolve the "air bubbles in the water" and "reduced pressure" issues. Those should be simple fixes.
#1) Air in the water may very likely be from the faucet aerator, as thehamguy suggested. The water looks cloudy, but it's not harmful.
Did you remove the aerator and see if that fixes the air in the water? If you are unsure of what we mean, please ask. The aerator is located where the water comes out of the sink faucet. It has a screen in it and unscrews from the faucet. Place a washcloth over the drain hole in case you drop the part, it won't go down the drain.
#2) Reduced water pressure. The water filter will eventually get clogged and the water pressure will be reduced, that's normal. If the dealer didn't do it, remove the filter cartridge from the housing as rawlus suggested.
It works like a whole house filter. Removing the (string/twine looking) cartridge will allow water to flow unrestricted and should take care of the pressure issue. Use care re-installing the (empty) filter housing. Be careful not to cross thread it, getting it back together correctly/securely. Test for leaks/drips.
Now I feel too lazy to go back and read through all the other posts for any further suggestions.
Perhaps, when you get your camper home from the dealer, start a new thread. That way you/we can go through each (non-warranty) issue, one at a time. As each problem gets resolved we'll tackle the next one. I'm sure you will get help from folks here if you will take the time, straightening out each item, one by one.
Hang in there, we're trying to help. Stay positive and remember, the Fall is a wonderful time to camp!
