Been showering frequently at the cabin with the summer heat. As refreshing as it is, it doesn't compare to my house with municipal water, which will blast the dirt, soap scum and top layer of skin off in short order.
I have: 20' gravity feed from storage tank to a 3gpm 12v Flojet. About 10' of 1/2 pvc to an L5. Using the outdoor shower head and flex hose that came with the L5 I measure about 1.25 gpm. Without that, straight out of the L5, I get about 2, which is about right for the average shower, I'm reading. But not much pressure.
So, what can I do to get a better blast?

More pressure. Basically you will need a bigger higher pressure pump. I have a 2.9gpm 12v pump and it to is pretty poor on the pressure side.
https://www.amazon.com/SEAFLO-Water-Pressure-Diaphragm-Pump/dp/B072PYSRZ7/ref=sr_1_7? dchild=1&keywords=12v+pump+6+gpm&qid=1595432582&sr=8-7
For the $100 these higher gpm pumps cost you can spend the same $100 and get a cheap shallow well pump that uses 1in fittings and is way more capable. 12v stuff gets expensive quick. I remember you saying you have a pretty large inverter?

We used these at our last house that had so-so pressure:

They seemed to help and I liked them. It's a cheap try any way

I wish ours had more pressure as well. We have been looking at these shower hose/heads. They are well spoken of in the RV world. Oxygenics Shower

Hmm, I have a couple of 110 pumps sitting around, need to take a look. But I hate to have to replumb, rewire, etc.. And I already upgraded from the 1gpm Flojet to the 2.9 not that long ago.

That looks like the ones the city came around and gave out when they wanted to cut water usage. I like a handheld though, the dog showers with me..

That's interesting. Stop looking and get one, and let me know! 
Thanks guys.

Try raising your pump up, get it as high as you can and your pressure will rise with it.

A standard shower head is 2gpm. 12v pumps even with 3gpm dont flow much. Rated flow is at no head. Start adding head and you loose gpm. Open a faucet and you loose psi.

Hmm, my pump is at ground level, 5 feet under the L5 and another 2 to the shower head.

Took a little road trip, stayed at a couple of motels. One had this shower head I really liked but I can't make out the brand. Interestingly the adjustment is at the base of the handle instead of rotating the head. One adjustment really put out strong pulses. I even took it off to check the output out of the plumbing, not any stronger than my cabin pump.
Anyone recognize it?
