Compact crawler obstacles

[Betts818]

Looking for some ideas. Here's the basic information for what I'm trying to do. I currently live in a double wide in a mobile home park. I have a decent size yard and a acre of property about 40 min north where I'm building a good scale course in the woods on where I'm going to move my home to in the next year or so. But......in the mean time it's getting old driving a hour and a half round trip to go trailing. I have a few local spots to hit also bit am looking to build some obstacles to keep put away neatly behind my shed and house and bring out when I want to play in my yard. I can not have anything permanent in my yard. Has to be moveable and being foldable is a major plus if possible. Was curious if anyone had any pics or ideas for some inspiration. Have lowes and Home Depot for resources for supplies. Thanks for any help guys. Also my rigs are 2.2s and a built wraith and a built scx10. Looking for fun and challenging with a relatively small foot print.
