Personally, I think RV manufacturers should make the bumper much smaller, to prevent folks from putting the sewer hose in there AT ALL. Doing so just leads to problems.
What happens is this: Every time you put that sewer hose away in there, you are trapping moisture inside that bumper. With time, the bumper rusts out as a result. Eventually, you'll get to replace that bumper because of the rust (although that will take several years).
However, long before that happens, you'll get to replace many sewer hoses, due to the rusty, abrasive surface inside that bumper scraping and tearing pinholes in your sewer hoses. Trust me on this: Your sewer hose is the LAST thing you want to have 'surprise' leaks in it when you go to use it to empty tanks. :)
This is why most folks quit using that bumper, and go to a vinyl fence post or PVC pipe setups, or use a bucket or storage tote. Your sewer hoses will last much longer that way. Also, 'tis nice to be able to keep all fittings on the hose all the time, and not have to take them on/off whenever you use them.
Do yourself a favor - Quit using the bumper for storing sewer hoses NOW, and store the hose one of the other ways mentioned. You'll be glad you did.
As to what sewer hose to get: Thats a subject of a lot of debate, too, as there's several choices out there. Generally speaking, though, I like to stay with the simple, standard vinyl hoses with regular, standard twist-lock adapters. The kind thats been around for a long time, is very common, and usually the least expensive.
Reason being, you never know when you may need to replace (or get an extra) hose or connector, and its best to have something standard/common that you can buy anywhere. These things never break at a convenient time or place, and you may have a tough time getting your hands on replacements if you have the more expensive, snazzy kind.
