I just put glow steps on my Northstar TC650 last week. They are extremely solid, well made and a bit pricey. If you add the landing gear the price goes up even more. However, to my mind they are worth it. They are rock solid, and the older I get the more important that is.
For the past four years I used a hitch step with a cheap step stool in front of it, which made two 18″ tall steps to get into the camper. It worked fine, but neither my wife nor I are very tall so it got to be a pain when carrying things in and out.
Only you can decide if the cost is worth it, but I can verify the sturdiness.
