Hi Jerry and Welcome to the group...
I am guessing that 2000 lbs is your tow vehicles (TV) limit. That being the case, most that weigh under that will have to have a dry weight
some somewhere around 1500 lbs. which leaves the Scamp
13 with front bath being about 90% of those that will fit the bill that may include a shower.
In looking at them you need to know that all 13' Scamps with a front bath may not have the shower and hot water option. Loaded and ready to go, our 13' with bath and hot water, but no shower weighed close to 1800 lbs.
There may be others, but the weight
limit, plus wanting a bathroom with a shower, will be limiting factors.
Good luck hunting and be sure to ask lots of questions.
