I use a barrel stand where the barrel is unloaded from my truck and onto its side onto the barrel stand. Not really that hard to do,..even by myself. And with two people it's really easy. Use 5 gallon buckets to transport what you will need for the day,..and if you have a roof tank,... have it filled before leaving.
I made my own stand that is VERY sturdy,..but the main benefit of homemade is you can make it the the exact height of your truck or trailer. Also,..the barrel stand doesn't have to be the typical type you see with the "cradle". Just make what is essentially a table top and use a couple of wheel chocks on either side so it doesn't roll. I actually use a couple of homemade wooden chocks.
I used sawmill 2"x 4"s ,...they are actually 2"x 4" and are much sturdier that "store bought" 2"x 4"s. And cheaper.
* Although, I have considered buying a trailer just for hauling SH and letting it in the upright position and using an electric pump to transfer. I may do that someday, but right now the stand works fine.
**Unless you can get a hand pump that has seals that are specifically designed for SH and can handle it,..I wouldn't bother spending any money on one. Just buy the the electric. I think if I were to do the electric, I would put a " T " and PVC ball valves on it so I could rinse it after using it to transfer SH.
