Clarification of Terms in Rental Agreement
My rental agreement states:

Automobile Repairs: Please do not repair cars on the premises (other than minor adjustments) unless you have written permission to do so. NO CHANGING OIL. No major repairs.

I own a purpose built 4 wheel drive vehicle which I use only for recreation. It is highly modified and built for the sport of rock crawling. I would like to understand to what degree the landlord is bound by the terms stated in the rental agreement. The term repair is defined as “To restore to sound condition after damage or injury; fix: repaired the broken watch”.

If I perform actions like modifications or improvements which are not the result of an intent to “restore to sound condition after damage” as repair is defined am I in breach of the rental agreement?

My jeep has four doors and a rear hatch. All of the doors and the rear hatch are removed when I take the jeep out on the trails. All of these items are very easy to remove; it totals 16 bolts and about half an hour of work. I feel this is a minor adjustment.

I would like a little help understanding to what degree the landlord is bound by the specific terms stated in the rental agreement.
