I wouldn't trim fenders or just put some foam it is fine. Just get the right rack for the job. Also keep in mind that the per bike weight is the important weight don't worry about total weight because if you are exceeding the per bike weight you are going to have problems. The Thule can handle 65 pounds per bike and can tilt out of the way easily when you need to access the trunk. Let's also not forget about the ramp so you don't need to lift the bike just use the walk assist and walk it up the ramp.
There is no "right" rack as all entail compromises. The Thule is not able to properly support two 70 lb e-bikes and the ramp is too short to be of use on an RV or truck. The Yakima has similar issues with a 140 lb load and it ramp is not without its problems. The Swagman E-Spec and the Hollywood HR1700 have no provision for a tramp and so the user with two bikes is going to have to lift a 70 lb bike waist high and lean over the rear most wheel holders to put the first bike in place. The 1up rack has a good ramp but it uses wheel holders that are best used with bikes without fenders. If you really thought this through you would already know this.
And by the way the Thule and Yakima and Hollywood and 1up e-bike racks have been out of stock for many months. The only rack at this time that will hold two 70 lb e-bikes and is available to buy is the Swagman E-Spec (if one searches diligently as they are scarce) and that means no ramp.
