You keep talking about "Tory Brexiteers" but you're still ignoring the non-Tories (including Brexit Party candidates) who back the deal and think Farage is wrong.
Here is one person who I have no doubt has read the agreement from cover to cover. He is the legal expert Martin Howe who was a sharp critic of May's deal, which he had forensically scrutinised.

In case you're not a Telegraph subscriber, the key argument I think is this:
"a word-for-word comparison of the Political Declaration (PD) which sets out the future EU-UK relationship with its previous Theresa May version reveals that it has been amended in vital respects. The PD is important because it is linked to a legal obligation on both parties to use “best endeavours in good faith” to negotiate an agreement in line with its principles.
The PD as amended now clearly foreshadows a Free Trade Agreement (FTA) with the EU and not a customs union. The difference is vital because an FTA, unlike a customs union, allows us to set our own tariffs with third countries and to operate our own independent trade policy.
Obligations in the PD for the UK to align our future rules to EU rules have been deleted, and any alignment will be optional. The so-called “level playing field” commitments in the PD have been changed. The previous commitment to shadow the EU rules on competition and state aids in Theresa May’s WA has been replaced with a more open ended commitment not to distort competition similar to that in many FTAs."
He does admit that some problems remain in Johnson's deal:
"But they do not make the deal Brino and do not stop us achieving the fundamental objective of Brexit which is to restore our independence and sovereignty over our laws, borders, money and international trade.
My own preference would be for us all to get into a time machine and travel back to 2016, avoid the disastrous May premiership and instead have a competent and determined PM conduct the negotiations with the EU. The enormous strides which Boris Johnson has made in changing a supposedly “unreopenable” deal in a few short months demonstrate that we could have got a wholly different and much better deal.
But we must deal with the world as it is rather than the world as we would like it to be. This is something that Nigel Farage should bear in mind now."
