We currently own a 17' Casita and tow it with a 4 wheel drive (2011) Acura MDX with tow package. It is rated for 5,000 lbs tow weight, and 500 lb tongue weight.
We use a Prodigy P2 proportional brake controller, Kurt 17,000 WDH and a sway bar.
Our current rig is rock solid. We easily cruise up over mountains at 55 mph (or maybe 50 mph for the very steepest grades) without high RPMs.
On the interstate when an 18 wheeler blows past us at 75 mph there isn't even a shudder.
The dry weight of our Casita is 2,480 lbs. My research of threads on the Casita forum indicates that the average wet weight is 3,230 lbs with a
hitch weight of 420 lbs. (average of numerous actual wet weights of similar 17' Casitas)
No I have never weighed our rig wet, but we tend to travel light.... And we don't tow long distances with full clean, grey or black tanks.
We are hoping to upgrade to a 21′ Escape.
It has a dry weight of 3,050lbs plus the approximately 300 lbs of options and accessories we will add.
We will travel fully loaded (for how we travel) more likely just slightly above 4,000 lbs wet.
We do NOT want to upgrade our tug. It is not an option.
We have are sadly far from retirement age, so we make two trips a year with a total of about 2 weeks out, and 4 days of driving total.
I know the Escape 21' has a larger, flatter front and so it is less aerodynamic than our 17' Casita.
I would buy an appropriate hitch scale to make sure we never got over 500 lbs.
I know that it is best to have a safety margin (and to not tow at capacity)
My question is - considering all our variables - are we crazy to follow thru with this upgrade?
I know there will be varying opinions, but I am all ears. :-)
