glad you are asking before buying.
saw a couple yesterday, have a ford 250 with gas engine. just purchased a used triple axle 3 slide 38 ft 5er. they were told it would work.
I was told to always look at cargo capacity ahead of pulling.
my brother says and does pull the said weight, but cant stop in emergency.
we just purchased a 2001 30 ft cardinal rear kitchen. we love it. have found there are many different floor plans. when our slides are in, we still have access to what we need. we like rear kitchen over the rear chairs.
do a detailed walk thru and check slides.
