I have spent the last several weekends working, tinkering, studying, and/or researching any and all issues related to camping in our new-to-us Casita
that we purchased in November.
I need some opinions from the experts. The previous owner gave us a Husky Knuckle Trunnion Bar WDH that he had been using with the Casita
. He towed it with a 2011 Ford F-150. I will be towing it with an '09 Kia Borrego V8 2WD rated to tow 7,500 lbs with up to 750 lbs on the hitch.
Based on my research, I want my hitch ball 1" higher than my trailer coupler assuming both tug and trailer are level. This meant that I needed to dissemble the hitch and invert the shank. It is my understanding that if you can't get it to be 1" then better a little over than a little under. OK after inverting the shank. . .
Coupler is between 21 3/4" and 22"
Hitch Ball is 23 1/8"
This means at the most, my hitch ball is 1 3/8" above the coupler. I assume close enough. Thoughts?
Also, on a flat surface I measured the front and rear fender wells of the tug before and after hitching. I also measured the Casita
frame front and rear before and after hitching.
It is my understanding that the Borrego, when using the WDH, should not vary more than 1/2" after hitching using the before hitching measurements at the front and rear fender wheels. Here are the results:
Before hitching front fender well: 32"
Before hitching rear fender well: 32 1/2"
After hitching front fender well: 32 1/8"
Aftern hitching rear fender well: 31 5/8"
So my goal was to stay within .5" front and rear.
Front, I was within 1/8" Nice!
Rear, I was 7/8" lower rather than the desired 4/8".
In other words, I have 3/8 of an inch more squat on the rear than I should based on my research. Thoughts?
FYI, I have never RVed, never towed, etc. Last weekend, after inverting the hitch shank, I did hitch up and take the Casita around the neighborhood subdivision at 25 mph. No problem. Also, gave me a chance to practice backing up into my driveway.
My plans are to take it out this weekend up the parkway at speed to see how it handles.
I was wondering what you thought about my measurement outcomes. I seem to be in the ballpark, but not exactly. How important is exactly? Or, at this point, is it just about getting it on the road and testing it?
