Yes the high cross winds makes for very bad/scary/white knuckle driving and handling experiences with our multiples of TT's, A's, B's, C's and somewhat with TC's. We have had all of these over our 54 years of so much RV'ing all over the USA including Alaska and all but 3 remote Provinces of Canada.
The one type of RV we have owned 4 of and still own one and tow it back and forth to Florida each year and other places is virtually unaffected by strong crosswinds or semi buffeting is our 3 Carriage 5th wheels. Hardly ever even feel it pull on our truck at all nor does it move around much in crosswinds. Over course, Carriage RV's are very heavy which sure does help. Our 4 popup trailers we'd owned in our very earlier past (very long ago) of course, were not affected by crosswinds.
Our 11'4" Lance truck camper on our Chevy diesel crew cab long box 4X4 truck we have and still use a lot in the warm season when our 5th wheel is not is somewhat blown/affected by very strong crosswinds etc. However, still nothing like our 3 big Allegro class A's or our other 2 class A's owned or our 13 various model 2 B's, 2 C's, and 5 TT's we have owned over the 54 years were. Always had 2-4 RV's at any given time since 1965 because we could and because no one type of RV is good or better for the way we use them which is so varied.
Just one of the many reasons we only have the TC and the 5th wheel today. Plenty good enough + for us at our 77 years old age.
