Oh boy... Any tips on what to do? Well you are doing what I know. Heat up the inside of the camper, leave all cabinet doors etc open to let heat in and wait.
On the drains, I do not know for sure but this might help, add some pink stuff now even if traps are froze over. Between the heat from the furnace and the antifreeze it can help penetrate the frozen trap gently.
The water pump, pending location if it is safe to do, point a small fan forced heater towards the end cap where the water is on low. Do not try and turn on the pump until you absolutely know it is thawed out. As if not the motor running may tear apart the diaphragm. I do not know your camper well enough to know if there is space to do the heater trick. You will have to make that call but what ever you do not leave the camper when you have it on and feel for excess heat often in the area it is blowing. Keep it a good foot or more away anything. Even if it is 2 to 3 feet away it is getting more warmth then jsut letting the camper warm it
The hot water heater, if it was full, hopefully it is only crusted over inside. I’m thinking using the electric element may be gentler then the gas to help thaw it. Did you drain it the last you used it? If so then this one is not so bad and for sure do not turn on the electric unless it is full of something. Since the HW heaters are insulated even room heat will have a hard time thawing it out.
Actually a thought has come to mind. Do you have a buddy with an enclosed heated shop? Take the entire camper and put it in the heated building plus run electric heaters inside with doors etc open. Sort of thaw it out from outside in and inside out.
Gentle heat would be key. I would not attempt to take anything apart until it has time to thaw soften up other wise the plastic may crack for sure.
The little fresh tank drain petcock, no I do not remember which way is which. I changed that dumb thing early on to a real valve.
