Trakmaster versus Evernew Off Road Poptop

We are after an off road poptop that is 7’ by 14’ with a combo shower and toilet with 80W solar. After some research we have narrowed down the list of choices to a Evernew or a Trakmaster offroad poptop. The Evernew with control rider suspension is around $44,000 and the Trakmaster Kimberley is about $18,000 dearer. We consider that the Trakmaster has a superior furniture finish but are not sure what other advantages we get for the extra cost. I understand that both vans could handle the Gibb River Road and the Tanami. Please advise any comments on benefits of spending extra cash on a Trakmaster. (Please note I have put this question on both the Caravaners Forum and the Exploroz Forum). Thanks Peter.
