As for extra water, I carry 450' of white hose! Normally run it out to nearest tap and fill...that was my solution for not having to haul 8 X 5 gallon jugs... Works for me.
All great repys guys-thanx. Likely just keep it as a spare.
The other issue I have is; I turn pump on..get great flow to washroom (both shower/vanity but it just dribbles from kitchen faucet? What could be the cause? No apparent air in system.
Thank you,
Stk

I kept my spare in the bedroom closet in case my new one fails. No water in the kitchen, try cleaning the screen in the faucet. Mine was full of sediment. Great flow now!

If you really want to play around with them to see what will happen with both in a parallel setup here is something to try. You will need some fittings,hose and a pressure gauge. First put a pressure gauge (0-50 psi) on the output of the pump you have installed now. Turn the pump on with nothing flowing-check the pressure. Now turn on a faucet and record the pressure drop if any. Now hookup the second pump in parallel and do the same thing. Most likely with both pumps in the system you will see much lower pressure drop with a open faucet. Is it worth the trouble? You will have to decide (-:
I recently replaced our original Shurflo 2.8 gpm pump with their 5.7gpm pump and it made a huge difference in DW's water pressure. Its now 65 psi and before it was about 40 psi.

Never hear of it, but: I'm thinking that they would argue with each other. One would detect a load pressure and think that there was no need for water so it wouldn't kick in.
Kinda' like hooking up two battery chargers to a battery, one would think that the charge is higher than it really is.

It would provide pressure at whichever pump is set higher, no more.
They would both kick in as soon as the pressure dropped below the threshold they are set for.
If enough faucets opened up they would both contribute.
You would definitely want to make sure that the wire size was suited for both pumps unless you add a new circuit for the the additional pump.
Depending on the inlet hose size, you may not have enough flow to even realize a difference.

Yes put it in the compartment next to the existing. Just cap off the connectors to keep clean and leave it there ready to install if needed. This way you will be guaranteed to never have problems with your existing pump.

If it was me, I'd hook the two pumps up in parallel so as to have redundancy always in place. Our water pump failed on an RV trip and it was a big pain.
The flow rate will be nearly doubled. The pressure will remain the same as one pump. The current to operate it will be doubled when in use, but since flow rate is also nearly doubled, the amount of current used will be partially compensated for because you won't have the dual pumps ON as long per use.
For the ultimate in reliable and flexible redundancy, install each pump with valving so you can use either pump separately, or both together in parallel!
Redundancy is priceless on RV trips!

pressure is an equation
pressure increases when the delivery line is smaller than the flow rate of the pump
pressure decreases when the line is larger than the flow can fill and maintain pressure, example couple a 1/2" line to a 3" line, at the open end of the of the 3" the water will just kind of run out, NOT spray out, it will fill a bucket at about the same speed/flow rate, but it Won't spray any where with force or distance
to build/increase pressure, one pump/pumping station is connected in series to the next pump/station
use one pump, keep the other as a spare
Options, always have options, and the journey goes much smoother

Could be many things. Start with the filter on the faucet, they get plugged up easily. Could be a kink in the line, are both the hot and cold slow or just one? If both are slow its usually something with the faucet.
