you'd have to look at the weight & towing capacity ratings (along w/ the gross combined weight ratings) of your coach as well as your hitch.
the 99 Wranglers weigh between 3045 & 3247 lbs (dry) depending on the model - then add the weight of the trailer plus your mods and liquids....id say its gonna be tight (unless you buy and expensive aluminum trailer).
IMO a wrangler is not safe to tow much of anything (the 99'stowing capacity is 2000 lbs maximum)...if you don't wanna tow the jeep 4 down then surely you don't want to tow anything behind it either.
Im also 6' tall & while our shower is big, its not like being at home either...the fact that i can take a shower & be comfortable (after riding dusty trails) is HUGE.
