For your 2018 Volvo XC90, I recommend using the Draw-Tite Max-Frame Trailer Hitch Receiver part # 76194 because this trailer hitch unlike the Curt Trailer Hitch Receiver part # C13233 will not require any drilling into the frame which is not exactly something most want to do on a brand new vehicle. The install process will be a bit more challenging but the limited vehicle modifications makes it well worth your while. We also have an install video of this hitch which I have attached for you as well.

In order to then couple the trailer to your newly installed trailer hitch you will need both a ball mount and hitch ball. For this, I recommend using the MaxxTow Adjustable-Height Ball Mount part # MT70067 because it has multiple adjustment slots to ensure the trailer is towed level with the 50mm Hitch Ball part # EH53C-C. For a trailer wiring harness, I recommend using the T-One Vehicle Wiring Harness part # 118683 because it is nearly entirely plug and play which you can also see in the attached install video.

I did some research on you 2018 Dethleffs 495 QSK and it looks to have braked axles which means you are going to need to convert the above 4-way to a 7-way and then install a brake controller. For these two items I recommend the Universal Installation Kit part # ETBC7 with the Tekonsha Prodigy RF Wireless Trailer Brake Controller part # 90250. The Universal Installation Kit requires hardwiring but there is no way around it and we have an install video for you. The Tekonsha Prodigy RF installs on the trailer so no modifications to the tow vehicle will be needed once the 7-way is installed. You only need to run the black 12 volt power wire to the battery on the Universal Installation Kit.

Unfortunately, there is no easy way to tow a trailer with a Euro trailer connector using a vehicle with a US trailer connector and certainly no way to switch back and forth. They do not make any sort of adapter for this to my knowledge and the only option I can offer you is to remove the Euro trailer connector from the trailer and install a US trailer connector. For this you are going to need both a converter box part # 118158 and trailer connector part # H20042.

On your trailer there should be the following wires:

Yellow: Left Turn Signal
Blue: Fog
White: Ground
Green: Right Turn Signal
Brown: Right Tail Light
Red: Brake Light
Black: Left Tail Light

When converting these wires for use with the US 7-way trailer connector you will need to make the following connections:

Euro Yellow = US Yellow
Euro Blue = Null
Euro White = US White
Euro Green = US Green
Euro Brown + Euro Euro Black = US Brown
Euro Red = US Red

In regards to hitch height, there isn't a standard for each country but the MaxxTow Adjustable-Height Ball Mount has multiple adjustments so you shouldn't worry.
