No matter which way you use the dolly...
I am reading your post (# 18) & got a good laugh. I actually moved the slant-front dryer I got this past weekend into the house last night to protect it from the big rains that were headed our way. I borrowed a dolly from work & purchased a strap to tie it down. However, with that slanted front it was not that simple! The strap kept slipping up under the top. I had removed the clips to hold the top down when I was first looking inside. So, there was nothing at all to stop that strap from slipping all the way up! And, man, that machine is so big, it barely fit through the doors!
