We just bought a trailer and had the water turned on. We have cold water coming out of hot water side in kitchen and bathroom. What could this be? Also we have good water pressure in the bathroom but very low pressure in the kitchen. What could cause this? We checked the breakers and it is on. HELP!! We are not knowledgeable at all on home improvements.

The troubleshooting section in the installation guide would indicate 2 things. First, you've likely backed the limit screw out too far - assuming the water pressure on the hot and cold sides are similar between the two showers, they should be set in the same range. Second (and more directly related to your issue), you should pull the spindle assembly and make sure it is clear of debris and calcium deposits.
The only time I ran into something similar it was due to a failed anti-sweat mixing valve on a toilet that allowed back-flow through the hot water pipes. That would also explain in your case why the kitchen sink doesn't seem to be effected by the issue.
About the only way I can think of to test this theory (without opening walls) would be if you can cut your cold water off to the bathrooms without cutting the supply to the hot water heater. In the unlikely event that you can do that, your toilets would still be able to fill from the hot water line when flushed.

Hot water will depend on the recovery time of the heater. Being off, it will take longer than normal since there is no residual heat. Does this water heater have any adjustable settings, an off, vacation or hold, or adjustable thermostat? I suggest waiting about half a day and see what it does. If it still is cold water temp, you have a wiring or element issue. If it is warm, wait until the next day and test again. If it's hot, you're good, still warm? Check elements or settings (if it has any).
As for pressure, have the water off, and I assume drained from the plumbing, you may have sediment washed into the aerator or valves. Pull your aerator of each sink, if it can be, and check for sediment. Clean and reinstall. If that doesn't help, try to open and close the valves under the sink a few times, check the aerator again.
