That's the spirit, Shawn- my favorite trips with my Trillium
have ALL been with the Grandkids....
Keep us posted!
Here's one more peabrained thought: This would be a radical solution, but if you can't go "up" with the opening, can you then perhaps go down
It occurs to my remodeler's soul that if one were to bust out the concrete directly beneath the door and dig down a ways, a "trough" might be formed that for everyday purposes could be bridged with, say, composite decking or some other attractive but relatively light
material. But when moving the trailer in/out of the space the decking piece could be removed, allowing the wheels to drop down and ride through the low spot.
Simpler still would be to do something similar, but just for the footprint of the Scamp wheels...a couple of strategically placed foot wide "troughs" perpendicular to the door and through that stretch would do the trick.
Just a thought from Make-it-Fit Central!
