a) You can't put a 5th wheel or gooseneck hitch on that bed.
A 5th wheeler and gooseneck trailer turns over the bed of a truck:
vs. the turn above will bump up against the side of the CyberTruck bed:
c) Can't put a camper over that bed. The haul capacity is also too small for most campers due to the SRW.
Are you referring to fifth wheels, or regular travel trailers? I don't know much about the fifth wheel ones because that's not what I want, but it seems like it should handle a regular ball-hitch travel trailer OK.
Referring to a truck camper. e.g.
This has a similar problem to the 5th wheeler - it needs space to hang over the sides of the bed.
Of course, the CyberTruck won't have a problem with a small travel trailer:
But you don't need a CyberTruck for that, you can tow that with a Model X today. Admittedly, you don't have the pretty significant benefit of the 240V power source of the truck.
Which leaves your large travel trailers:
The CyberTruck will do fine with these, but these are about as aerodynamic as a Home Depot, so count on cutting your range in 5. These are also NOT fun vehicles to travel with - they're more meant to be left at a destination for a long time. But a CyberTruck with its 240V power source is meant to supply power for a short time (< 1 week), so it's not a great synergy.
The perfect combination with a CyberTruck IMO is a Truck Camper. You don't have the SuperCharger "fit" issues of a trailer, they are the best suited for off roading - which the CyberTruck will be great at due to the clearance, and the Truck battery makes it ideal for off grid. But the bed design of the CyberTruck makes it impossible.
Of course tent camping works, but tent camping works in a Model X too - and with a Model X tent conversation you can use the climate system of the car in the tent, which I don't see happening with a truck bed:
