33' is pretty unusual, esp. for a Patriot. It would help, whenever you want assistance regarding your coach, if you include more information. Many of us put our basic coach info in our Signature or Member Profile so it's visible with every post we make. Model year, for example, would be good to know here for readers that might be able to answer your questions.
That said, most 12 volt system fuses or circuit breakers are in the front driver's side bay on most coaches. It's also possible, since I believe you've said in a prior post that both seats' adjustment switches are inoperative, that there is a master fuse under the dash or elsewhere for that function. Hopefully someone with experience with a similar model and year will chime in here, once you post more info.
Not sure about your specific brake fluid reservoir location, but Gerald or someone probably will steer you in the right direction.
Tire pressure should be posted on an ID plate or two on the driver's side wall behind the driver's seat. However, it is safe practice to get your coach weighed while fully loaded, and know its individual wheel weights. RVSEF (Recreational Vehicle Safety & Education Foundation) can provide that service to you at many large rallies, or you can get at least front and rear axle weights at state or commercial scales. RVSEF will send you coach-specific pressure recommendations a short while after weighing the rig. If your coach is older, also make sure the tire type and size is appropriate to your motor home - who knows what a previous owner might have done.
And if you are just learning, you should, by the way, try to attend an RVSEF safe driver seminar/course, also at most large rallies. If you can get to the FMCA convention in Redmond, OR, next month, DO IT! You will learn more there than you ever imagined, as you will at a BAC rally where you meet people with rigs and experiences most like your own. Most importantly, you will be a safer RV driver - for yourself and the rest of us that share the road with you.
You've already taken a great first step by joining the BAC and using the Forum to help become familiar with your Patriot.
