Got you beat. My 650 KLR gets 70+ depending on how far I twist the handgrip.... The RV industry just took a massive sucker punch. No one in their right mind (unless they were extremely flush) would buy a fuel sucking land yacht, to go 'Glamping' in.
The auto makers are also going to take a sucker punch as well. The big push (was) for land yachts and big pickup trucks, not fuel efficient cars so they just got caught with their drawers down as well.
I too have an RV but it's a truck camper and it's kept inside in the big barn when not in use. 7 years old and just like new. They last forever when kept inside and unlike a gas guzzler single purpose RV, the camper goes in the farm truck bed for trips and comes out when not.
