i put them on mine partly because my family's pop-up had them when i was a kid, but also figure if i ever camp somewhere that isn't entirely level it'll be good to have a nice, stable triangle to support it and/or help level it out. sucks sleeping on an incline, ya know. not to mention potential weight of full coolers, water jug, camping gear, dishes etc in the back, but i dunno what you intend to have back there...
anyway, i put 2 of these on the back of mine...
just a thought though.. .
Most likely, coffee pot, a toaster, 2 burner stove, pot and pan, plastic totes for canned goods, a croc pot when electric is available..At some point, I want to get a short wheel base full size van for tow vehicle, or a small suv..
I am going to sell my little green teardrop. Will post it in the for sale forum here first. Danny
I'm back 
Had a lot of health issues the past few years, getting old. But, getting the itch to build something again. 
I still have wood and tools.. look out!!
