I have a 2006 Pleasure-way Lexor Td on a 2005 Chev chassis.
I love it
the 6.0L is well sized for the weight, gearing is good for mtn driving- not just pulling uphill, but for slowing on grades. that keeps the brakes fresh
mpg is at 15 on the hwy...a bit better when without ethanol....it's pulling close to 9000 pounds and punching a big hole in the air.
Speeds above 75 are squirrely...70 is nice
If used, the hitch will hold 500 tongue weight, 5000 pulling.
a scooter can be tricky on the back as some have all the weight at the rear. make sure you can get a good balance- I've seen lightweight carriers break under a scooter with all the weight at the rear
I use a 77 honda trail 90, the weight is balanced.
both vehicles and the genny use the same fuel ( gas). I don't think diesel is as much an advantage as it was years ago.
a prime mover for me with choosing Chev is that I have other GM's and am familiar with the chassis.
kick some tires, look at youtube videos from dealers showing features and see what lay out appeals to you.
a word of warning- I was all hot on an 09 Era. the chassis was fantastic and it drove great...the quality of the coach build was shockingly bad.
