Trailer Question

never cross the rear because like the op's rig β gets too big
never a problem w/ side movement,
Yes the straps tend to loosen a bit, I put that down to stretch.
As β increases and approaches 90 a approaches 0

I do not believe in crossing strap, especially in back, if for whatever reason you have a failure on one strap there is nothing to keep the car from moving forward.

I've been towing with an 8045 for 4 years now. RS then GT4. It's an awesome trailer, and I think you will come to love it. Love your car BTW.
As people have pointed out, you have WAY too much weight on the tongue. you should be shooting for about 700-800, I'd guess you have 1500+. You also need the hitch to be 19", it's too low, which is why the suspension on the trailer looks like it does.
The 8045 is setup for a 911 or much shorter car. You can actually move the axles forward to help with the weight distribution of a car with the CG much further forward. TailEX has amazing support, they can help you get it figured out. If you have or can find corner weights for the car, and along with the wheelbase, you should be able to calculate where the axles should be, along with the position of the car. PM me if I can be of assistance. I have a model of the trailer to help figure out the position of the car/axle, etc - but first talk to TailEX.

The straps should not loosen at all if they are tightened properly. Nor should they stretch enough to cause them to loosen. The material is designed to not stretch.
There is a video on Mac's site that says you need to get two full wraps around the mandrels which is about six full cranks of the handle. I had a problem with my straps getting loose. I was not getting those two full wraps around the mandrels. Now I get at least that many and my straps never come loose now.

I know that 24' is the way to go...I just don't want to spend that extra $$$, nor do I want to buy a new tow rig. I have towed a 20' enclosed before, and it was just fine for me...true, no cabinets....that extra 4', but I'll make do....appreciate the advice.

I have been talking to Carl at Trailex and he has been helpful - I also try to source some information from forums because I don't want to be his neediest customer

I was under the trailer yesterday and definitely see how the axles can move. It looks like the wiring might need to move a bit too but nothing too extreme.
THANKS for the offer!!! Here are my corner weights - posting here as they may be of interest for others.

Even the best high performance Dynema, Vectran, and Zylon(PBO) stretch
This is the reason harness manufacturer want their safety harnesses as short as possible. Same reasoning applies to cargo tiedowns.
I spent 30 years sailing semi pro and am very familiar w/ the friction and stretch characteristics of these materials. On a sail boat the long length of the lines exacerbates any stretch that is present, same w/ tying the boats to a trailer, very long straps are needed stretch and vibration are big issues.

all straps stretch, Polyester less so than nylon , but they all stretch. Most tie down straps are Polyester and most recovery straps are nylon.

We don't need your resume and we are not tying down sail boats here.
Notice I said "stretch enough to cause them to loosen". They are designed to not stretch but they all stretch a bit. In our car trailer application, they should not "stretch enough to cause them to loosen" just driving down the road if they are "tightened properly".

I have an open Trailex and have never crossed the straps. Don't like putting so much cross-stress/force on the suspension and risking to mess up or loosen the alignment. As for loosened straps, the proper procedure is to stop 5-10mins after starting the trip (typically right before you get on the highway) and re-tighten all straps. If this is followed, the straps should be as tight as you left them.
