So as previously mentioned this is our first camping season with a pop-up. I camped as a kid all the time. My parents had a small tongue trailer and when I was in my teens they upgraded to a 5th wheel so the whole tent trailer thing has been new. One of the things growing up I always hated was helping dad level the trailer or 5th wheel. Pull forward guess how much wood to put down, back the trailer up only to realize you put to much or not enough. It was a big pain in the keister especially when all we wanted to do was just enjoy camping. Well fast forward to getting ready to camp. Thankfully on the side of the house we are pretty darn level so no need to do any tweaking there. But I knew once we got into the mountains there I would be with two kids (under 4) itching to get out of the vehicle after the long ride, and my wife and I trying to get the trailer as level as possible before unhitching. I don't remember who but someone posted about these Andersen Levelers I forked over the $40+ dollars and ordered one. THIS WAS THE BEST PURCHASE EVER! So easy to use. Just identify which side needs to go up and my wife watches the bubble as I back up or pull forward, hollers stop and boom we are level! Well side to side at least. I ended up buying one for my dad for father's day and he didn't fully understand why. I told him give it a go. Well this Friday we leave for a weekend trip with my parents and I am sure he will be a believer after using this thing. What other awesome gadgets help make set up easier for you?
